Configuration and Initialization of RTEX Communication System 2-1 Outline MINAS-A5N Series equips the communication ASIC “MNM1221” which can be functioned in combination with 100BASE-TX PHY (physical layer chip) conforming to IEEE 802.3. You can compose 100 Mbps real-time communication system of Master-Slave method that suits to multi-axes servo control, by ring-connecting the slave (MINAS-A5N series etc.) with the master (host controller) equipped with the same MNM1221. MNM1221: Option No. DV0P444 2-2 System structure CPU MNM1221 Host Master PHY RTEX RX RX RX PHY PHY PHY MNM1221 MNM1221 MNM1221 CPU CPU CPU Slave MINAS-A5N Node address = 0 MINAS-A5N Node address = 1 MINAS-A5N Node address = n (n <= 31) Node address is the ID (MAC-ID) used to identify the slave on the network, and set up with the rotary switch (RSW) on the front panel. For the master produced by using the sample code provided by us, the node address setting procedure shown in the figure above will not be required. Notes: • A Hub required in standard 100BASE-TX is not used because of ring topology. • In the above figure, pulse transformer which is connected between PHY and connector and other components are omitted. • Use the STP (shield twisted pair) cable of Category-5e or upper specified by TIA/EIA-568 Standards for the communication cable. R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 3 - 2-3 Basic specifications of network The following describes the basic specifications of the network interface. R2.0 Item Specifications Topology Ring Physical layer 100BASE-TX (IEEE 802.3) Baud rate 100 [Mbps] Network Status LED [COM], [LINK] 2 units Setup of node address (MAC-ID) Rotary switch (2-digit) on the front panel Setup range: 0 to 31 (Default 0) Communication cycle (physical data transfer cycle) 0.0833, 0.1666, 0.5, 1 [ms] Command update period 0.1666, 0.5, 1 [ms] Control mode PP: Profile position mode CP: Cyclic position mode CV: Cyclic velocity mode CT: Cyclic thrust mode Connecting cable STP (shield twisted pair) cable conforming to category 5e or more of TIA/EIA-568 standards. Note: Use the straight wiring. Cable length a) Inter nodes: Max. 100 [m] [Under review] b) Total: Max. 200 [m] [Under review] Note: Use within the range which satisfied both of the above conditions. Consult with us when you use exceeding the above b) condition. Slaves to be connected (axes) Max. 5 when communication cycle time is 0.0833 ms Max. 10 when communication cycle time is 0.1666 ms Max. 32 when communication cycle time is 0.5, 1.0 or 1.0 ms Notes: • Number of axes when all connected axes are in 16-byte mode. When in the 32-byte mode, the number of axes connected is one half that of axes connected in the 16-byte mode because the number of transmit-receive data blocks is twice that required in the 16-byte mode (fractions omitted). • These figures depend on the arithmetic processing power of the host device. Data size 16-byte mode: Transmit/receive 32-byte mode: Transmit/receive Communication error detection CRC-CCITT Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 4 - 2-4 Node address (MAC-ID) setting and front panel configuration The figure below shows the front panel configuration of MINAS-A5N series. LINK LED Rotary switch (RSW) for node address (MAC-ID) setup Setup range: 0 to 31 COM LED 7-segment LED (2-digit) Connector for analog monitor (X7) Pin No. Symbol Description 1 AM1 Analog monitor 1 2 AM2 Analog monitor 2 3 GND Signal ground 4, 5, 6 - Reserved (Do not connect) • Set the node address (MAC-ID) in a decimal number: high order digit on MSD rotary switch and low order on LSD switch. Example: When MAC-ID is 13, MSD = 1, LSD = 3. • Node address (MAC-ID) set with the rotary switch will be loaded once when the control power is turned on. Therefore, a change made after the power up will not be reflected to the control but will become active upon the next power up. • Do not change the value of the rotary switch in power on to avoid a trouble. • Setup range of the node address (MAC-ID) is 0 to 31. If the setup value exceeds 31, Err 82.0 (COM invalid node-address protection) will be occurred. • The host controller (master), when transmitting, should specify the node address (MAC-ID) in Byte 0, bits 4-0 of the command. If the node address is different from the address specified by the servo drive, Err 86.0 (Cyclic data error protection 1) will occur. R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 5 2-5 Communication cycle/command updating cycle, control mode and data size setup Designation Description • The cycle at which command or response RTEX frame is transferred.

Transmission Protocol of RTEX Communication Data 3-1 Transmission timing of data • If the synchronization between the communication and servo is not established, the command receiving timing and response transmitting timing are unstable. The timing diagram in this chapter shows established synchronization which can be verified through the logic output signal (extended portion) of the monitor command. • Because the echo back of the Update_Counter is generated in the data exchanging process of the servo driver, the echo back (Update_Counter_Echo) is immediately returned unless a communication error occurs. • In contrast, the echo back (Command_Code_Echo) in response to the command code is not immediately returned because it is generated in command/response process. Relationship between Update_Counter and command code may not be the same for transmitted data and received data. • If the control mode is switched to a different control mode when the communication cycle is 0.0833 mm or 0.1666 ms, the response timing of the command code echo back is different from the response timing of internal data e.g. position deviation which depends on the control mode. For details, refer to timing diagram in 3-1-3 and 3-1-4. • If the command is not correctly received due to problem caused by command code or argument, the command error bit (CMD_Error or Sub_CMD_Err) is set to 1 and returned. When the servo driver correctly receives the command, the command error bit is set to 0. For secure command transfer, hold the command code value until the echo back is received.

(Set also Type_Code, Index, Command_Data3, etc., at the same time or beforehand.) 2) Hold the command until the normal echo-back is returned. 3) When normal echo-back is returned and Busy bit is 0, get the necessary data after checking ERR bit and WNG bit. After that, bring the command code back to the standard command (e.g. normal command: 20h). Standard command 10h, 20h, 30h, 40h Description These are reference command for handshaking when transferring non-cyclic command. Normal command (0h) serves as standard command. ▪ If a sub-command, Sub_Command_Code = 0h is the standard command. The change of command code is the trigger for executing the process. Only one process will be executed per one trigger. Example: Operating procedure of non-cyclic command when changing parameter When changing the multiple parameters continuously, it is necessary to bring the command code back to the standard command (e.g. normal command: 20h) every time a parameter is changed. Note that the process will not be executed only with changing the parameter number. Example of parameter command (Command: 26h) : (For position control, and standard command is 20h.) 1st process Command_Code 20h Standard command 20h Standard command 26h time 2nd process 20h Standard command 26h *2) Command_Code _Echo Busy (Parameter processing at the servo driver) 20h Standard command 26h 20h Standard command 26h 20h Standard command *1) *1) Parameter process will be executed in the servo driver at the transition from normal command (20h) to parameter command (26h).

SL_SW EX-OUT2 EX-OUT1 R2.0 • Set up the thrust limit switching command. • This signal is enabled when Pr.5.21 (Selection of thrust limit) is set to 3 or 4. ▪ See section 4-2-3-3 for details. • Set up the speed limit switching command when controlling the thrust (CT). • This signal is valid when parameter Pr.3.17 (Selection of speed limit) is set to 1. ▪ See section 4-2-3-4 for details. • Select the external output signal RTEX operation output (EX-OUT1/EX-OUT2). 0: Output transistor is OFF; 1: Output transistor is ON • This signal is enabled when RTEX operation output (EX-OUT1/EX-OUT2) is assigned to interface connector X4. • This signal does not affect the servo control. ▪ See section 4-2-3-5 for details. Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 29 4-2-3-1 Servo_On/off command (Servo_on) Use this command to energize (servo on)/de-energize (servo off) the motor. • When external servo on input (EX-SON) is assigned, the servo-on command for servo control process is enabled as both external servo on input (EX-SON) and this bit are in servo on state. When the external servo-on input (EX-SON) is not assigned, only this bit is enabled. External servo-on input (EX-SON) AND Servo-on command for servo-on control processing RTEX servo-on command (Servo_On) <RTEX communication: External servo-on input (EX-SON) is assigned> • Servo-on command cannot be used, if the servo is not ready for operation (in alarm condition or main power source is off ), or motor is running (at 30mm/s or higher). Servo-ready condition can be verified by checking Byte 2, bit 6 (Servo_Ready) in the response. • During servo off (clearing positional deviation), the command position in the servo driver follows up the actual motor position to minimize the positional deviation to 0. Therefore, to start CP control (cyclic position control) after servo is on, re-set the coordinate system of the host controller with servo-off state, set the actual position value to the command position, and then transmit the servo-on command. For detailed description, refer to Section 7-1-1. • When the servo is turned off while the profile position control system is operating (In_Progress = 1), the profile process is canceled. • During servo off, servo internal process remains position control even if cyclic command is CV/CT. Instructions for use of the setup support software PANATERM and linear motor automatic setting software MotorAutoSetup • When running “test run function” or “frequency response analyzing function (FFT)” by using the setup support software, PANATERM and linear motor automatic setting software MotorAutoSetup issues servo-on command by each setting tool. This command is also enabled when the external servo-on (EX-SON) is assigned. If the external servo-on (EX-SON) is not assigned, only the servo-on command by each setting tool is enabled. External servo-on input (EX-SON) AND Servo-on command for servo-on control processing Servo-on command by PANATERM and MotorAutoSetup <When PANATERM and MotorAutoSetup is used: external servo-on input (EX-SON) is assigned> • While running “test run function” or “frequency response analyzing function (FFT)” RTEX communication and each setting tool cannot be used (should be previously turned off). • Monitor value of servo-on input state on PANATERM is “servo-on command to servo control process”.

However, this is confusion because some functions are enabled and some are disabled upon changing control modes: Ideally, functions allocated to a terminal should be common to all control modes. • Because the following pair of designations is assigned to the same bit position, only one of designations can be selected: SI-MON1/EXT1, SI-MON2/EXT2, SI-MON3/EXT3, SI-MON4/EX-SON and SI-MON5/E-STOP. If attempt is made to allocate 2 or more functions to the same bit, Err.33.0 (I/F input multiple allocation error 1 protect) or Err.33.1 (I/F input multiple allocation error 2 protect) will be enabled. • This status returns the logical status (1: function active) but not physical status (input transistor ON/OFF state). However, status of driver inhibit input (POT/NOT) can be logically set. • EXT1, EXT2 and EXT3 indicate the state of input signal but not complete state of latch. • For driver inhibit input (POT/NOT), status response condition, status bit arrangement and status logic can be set as shown below while the function is disabled (Pr.5.04 = 1), through the parameter Pr.7.23 (RTEX function extended setup 2).

Return 0 Return 0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 55 6-3-1 Software reset mode (Type_Code: 001h) Use this mode when resetting (restarting) servo driver without turning off control power (software resetting). Reset process has to be executed after confirming that the all of servo drivers have received reset command (1h) normally, because it is necessary to reset surely all servo drivers even if the communication error occurs. For this purpose, the servo driver resets itself at transition from the reset command (1h) to normal command (0h). If the communication error occurs at transition from the reset command to normal command, there might be case that only some of the drivers can receive the normal command. In this case, the servo driver also resets itself if the communication time-out has occurred in the condition that the last command was Reset command (1h). The following shows the procedures to reset servo drivers. 1) Change command code of all servo drivers from normal command (0h) to Reset command (1h). Also, be sure to set Type_Code to 001h and Index and Setting_Data to 0. 2) Confirm that the value of Command Code Echo sent from all servo drivers is (1h), and then return to normal command (0h). 3) The servo driver will start executing a reset process when normal command (0h) has been received normally, or when the communication time-out has occurred in the condition that the last received command was Reset command (1h). 4) Since there is no response from servo drivers due to the reset state, the master will detect the communication time-out. When the time-out is detected, reset the communication ASIC (MNM1221) and initialize the communication again. time Command code to all servo drivers 0h 1h 0h Td Command code echoes from all servo drivers 0h 1h Return to normal command (0h) after checking echoes from all servo drivers. Reset process on the servo drivers Note: During resetting process, output signal (output transistor) is OFF.

When validating attribute C, it is not necessary to write this parameter to EEPROM before executing the command (prewriting is optional). Because the parameter of attribute R becomes effective only after resetting, it is not made effective by this command. Reset the control power source or perform software reset (Type_Code = 001h). In this case, it is necessary to write the parameter to EEPROM beforehand. For attribution of a specific parameter, refer to Technical Reference, SX-DSV02309”Section 9-1”, Functional Specification. • When this command is received in servo-on status, it causes the command error (0045h).

When using HOME, POT and NOT as home position reference trigger, HOME can be allocated only to SI5, POT only to SI6 and NOT only to SI7 through a contact. Note: When POT or NOT is allocated to the latch correction terminal, a contact is used: drive inhibit input is not active when cable is disconnected. Therefore, safety must be secured by a different measure such as mechanical stopper.

Subsequently, when the host controller issues a command and motor moves, initialized motor position may deviate from the target position. If this positional deviation may cause problem, use the command position set. Expected application: Homing using stopper ▪ See 7-2-3-4.

As a result, the motor position is initialized to the presumed position even if the motor moves after the host controller has issued a command provided that the internal command position (after filter) is stopped.

While in the latch mode, Busy as latch process remains 0. This means that any other command e.g. parameter command can be executed while in the latch mode. However, commands that initialize position information, such as reset command and homing command (except for latch mode) forcibly cancel the established latch mode. 2.0 Note: In Latch trigger signal, Latch detection time has a difference with Logical rising edge and Logical falling edge.

Operation 7-1 Cyclic position control (CP) operation When the cyclic command (Byte 1, bits 6–4) is 2h and in servo-on condition (Servo_Active: response Byte 2, bit 7 is 1), perform positioning operation according to the given command position (absolute position: Bytes 4–7). You have to pay attention to the following. 7-1-1 Command follow-up process (command position at servo-off) For the cyclic positioning (CP), position command is given as absolute position. Therefore, if the actual position is changed by an external force, the position will return back to the command position upon the next servo-on if the command position is kept. This operation may cause Err. 27.7 Command error protection or Err. 26.0 Over-speed protection in certain condition. Do not apply the movement command during servo-on, even if the direction is drive inhibit input. To assure safety, when servo is off (Servo_Active = 0), be sure to set the actual position value read from the servo driver to the command position (command position follows up the actual position). Bad example: Command position at servo-off (Command position is not set with actual position) Command position (Command) Servo-on Response Servo_Active=1 Actual position Command position (Command) Equipment is moved by external force Servo-off Actual position Response Servo_Active=0 Command position (Command) Danger: Equipment returns to command position rapidly.

R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 105 - (1) When using CMD_POS Invalid bit (Pr7.40-bit0=0) Regardless of status of magnetic pole position estimation, Servo_Active bit of RTEX status is 1 when servo is on. (Motor is in activated state.) Example: Movement during CP control, Pr7.43=7 1. After control power is turned on, make CMD-POS_Invalid bit 1 under the state of servo-off (Servo_Active bit is 0) and make command invalid. 2. When turning servo on (make Servo_On bit 1), magnetic pole position estimation is implemented. 3. During magnetic pole position estimation, magnetic pole detection completion output (SI-MON4/EX-SON bit) turns to be 0. After confirming that magnetic pole position estimation is finished normally and magnetic pole detection completion output (SI-MON4/EX-SON bit) turns to be 1, set command position at value of actual position (APOS) and make CMD-POS_Invalid bit 0 and make command valid. After servo amp receives CMD-POS_Invalid bit =0, command position is made valid.

After completion of magnetic pole position estimation, Servo_Active bit of RTEX status is turned to 1. Example: Movement during CP control, Pr7.43=7 1 After control power is turned on, if turning servo on (make Servo_On bit 1), motor is activated while Servo_Active bit remains to be 0 and magnetic pole position estimation is implemented. 2. During magnetic pole position estimation, magnetic pole detection completion output (SI-MON4/EX-SON bit) and Servo_Active bit are turned to be 0. During this, set command position of upper device to value of actual position (APOS) and make command position follow actual position (APOS).

R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 107 7-1-3 Prohibited matter of NOP command (0h) NOP command (0h) is designed to be used for transient transmission while “the data to be transmitted is not yet prepared” due to processing timing problem until network is established. Therefore, try to transmit regular command e.g. 20h that specifies control mode, as soon as possible and never try to transmit NOP, and not to try to retransmit NOP. If NOP command is transmitted while the motor is running in the cyclic positioning (CP) operation, the servo driver controls at the command position determined by the previously received command, and the cycle is unchanged as if the stop command is received. Never transmit NOP command which causes unstable operation. Bad Example: NOP command (00h) is inserted during position command (20h) Time Data update period NOP cycle Command position The same as stop command Difference of command position (command velocity) 7-1-4 Command position upon communication error If communication error (CRC error, missing data, cyclic data error) occurs during CP control, control the command position at the estimated position.

Allowable input movement command value of servo driver (variations of command position during 1 s multiplied by the electronic gear ratio) is 400 M pulses/s. The movement command should not cause variations that may exceed the smaller one of these limits. If a variation of command position during communication period is too large, Err. 27.4 (Command error protection) will be activated. 7-1-5-2 Wrap rounding command position If a variation of command position during communication period has exceeded 7FFFFFFFh, wraparound process starts.

Note that, as in the case of 7-1-4-1, change the command position (CPOS) gradually by dividing the command updating period in several sub-periods so that variations in command position will not exceed the limit.

With MINAS-A5N, the following return-to-home sequences can be used. Sequence Description Cyclic homing The host controller controls the return-to-home sequence in cyclic position control (CP) mode. Profile homing The servo driver controls the return-to-home sequence in profile position control (PP) mode. For profile homing, refer to 7-5. Note: Return-to-home (except for multi-turn data clear of absolute encoder) cannot be started in the velocity/thrust control mode. Switch to the cyclic position control (CP) mode or profile position control (PP) mode and start the homing operation and then return back to the previous control mode.

Initialize the position information so that Homing_Ctrl bit is 1 and trigger detection position is zero. When Homing_Ctrl bit is 0, the position information is not initialized upon detecting of the trigger signal.

Even if Pr.7.23, bit 5 = 1 (start upon changing of command code and command argument), the normal command (20h) is required to pause the homing process. *2) In the incremental mode (incremental scale), internal command position and actual position are at 0 (home position) at power up. Until homing process completes (home position is set by trigger signal), apply the command position with reference to this 0 (home position). 2.0 *3) Using Type_Code, select the logical rising edge and logical falling edge of the sensor(HOME, POT, NOT, EXT1, EXT2, EXT3) or Z-phase as the trigger signal. For the trigger signal, refer to 6-5-1. *4) Homing complete bit will be 0 when Homing command is accepted. Note that it is 0 at power-up until homing is completed. However, if the homing is started with Homing_Ctrl = 1 at communication cycle 0.5 ms or more and then the trigger signal is immediately detected, Homing_Complete will not be set to 0 but set to 1 after the completion of the process at the first response. The homing process is successfully completed when no command error is detected, echo back value is returned and Homing_Complete = 1. *5) Homing complete bit will be 1 after homing is completed. While the command code is holding 24h after Homing_Complete bit switched to 1, the servo driver will ignore the command position and will stop the motor (servo-lock) at detected home position. Note that during feedforward the value remains valid. If this causes a problem, keep feedforward value at 0 during homing process. During the process, be sure to set the command position to 0 (home position). When command code is started with normal command (20h) or another command, operation will be started by a command according to the new reference.

Even if Pr.7.23, bit 5 = 1 (start upon changing of command code and command argument), the normal command (20h) is required to pause the homing process. *2) Do not change command position (byte 4–7) to prevent a trouble. (You must set the actual position/command position when the motor is not rotating.) *3) Homing_Complete bit will be 0 when Homing command (actual position/command position set) is accepted. Note that it is 0 at power-up until homing is completed. However, if the communication cycle is 0.5 ms or more, Homing_Ctrl will not be set to 0 but set to 1 after the completion of process upon reception of the first response. The homing process is successfully completed when no command error is detected, echo back value is returned and Homing_Complete = 1. *4) <Actual position setup> The actual position is set to the value of Setting_Data (Bytes1215) and the command position in the servo driver is also set to this value, the position deviation becomes 0. Position information after operation Actual position = command position = setting value (Setting_Data) Position deviation = 0 <Command position setup> The command position in the servo driver is set to the value of Setting_Data (Bytes1215) of the command, and the actual position is set to the command position after setup minus position deviation value. The deviation is held. Position information after operation Internal command position = setting value (Setting_Data) Actual position = internal command position (value after setup as shown above) – position deviation Homing complete bit will be 1 after homing (actual position/command position setup) is completed. R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 112 *5) At the time Homing_Complete bit is set to 1, the servo driver will ignore the command position and will stop the motor (servo-lock) at detected home position while command code is held to 24h. Note that during feedforward the value remains valid. If this causes a problem, keep feedforward value at 0 during homing process. When setting actual position, during this period, be sure to change the command position in the command to the actual position set. At the time the command code starts the normal command (20h) or another command, the driver will operate according to the command based on the new reference.

Control the motor velocity with observing the sensor signal level, and operate Homing_Ctrl bit. Note 1: When performing return-to-home by specifying the drive inhibit input (NOT/POT) as the reference home position, be sure to set Pr.5.04 (Over-travel inhibit input setup) to 1 to disable the over-travel inhibit input. Otherwise, Err. 38.2 (Drive inhibit input protection 3) will occur. Note that even if the inhibit input is disabled, the driver receives the signal and can use it as home reference signal. Note 2: When performing home offset, do not use the actual position set but use the command position set. The actual position set may produce a deviation equal to the position deviation. R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 114 7-2-3-1 Example of cyclic homing operation 1 Below shows an example of return-to-home operation in the cyclic position control (CP) mode using the combination of sensor signal (HOME) and Z-phase of feeback scale. In this example, the first feeback scale Z-phase after passing the sensing area of HOME sensor (position where one revolution data is zero) is the home. 1) Set Type_Code to Z-phase (011h) of feeback scale and set Homing_Ctrl bit to 0, and then change normal command (20h) to homing command (24h). Hold homing command (24h) until homing process completes. 2) Execute the positioning to rotate the motor at 1st velocity according to command position, which is based on the position at power-up. 3) Slow down the command velocity (2nd velocity) when the rising edge of HOME is detected with HOME bit of response. 4) Set Homing_Ctrl bit to 1 when the falling edge of HOME is detected. 5) When the servo driver detects Z-phase of feeback scale, it will set Homing_Complete bit to 1, ignore command position and stop the motor (servo-lock) at home position (single turn data is zero). Note that during feedforward the value remains valid. If this causes a problem, keep feedforward value at 0 during homing process. 6) After confirming that Homing_Complete bit has become 1, set Homing_Ctrl bit to 0, and then set 0 (home position) to command position. 7) Change the command code to the normal command (20h). Then, positioning will start according to the new reference. Therefore, be sure to perform step 6) before changing the command code to the normal command.

(It is internal operation value of the servo driver.) *2) If the falling edge of HOME is close to Z-phase of feeback scale, the delay of detecting HOME may make differences of a single turn between the detected home position and the proper home position. Install the motor at the position where Zero position of the encoder will deviate with 180 degrees (half-turn) at the mechanical angle from the falling edge of HOME. The Z-phase of feeback scale (position at which single turn data is zero) can be checked by using the following method. When using serial communication type incremental feedback scale Method Position where indicated value is changed when parameter Pr. 7.00 (LED display) is set at 7 and Z phase counter is indicated on 7-segment LED. When using ABZ phase output type incremental feedback scale Method Position where signal is changed when original signal of Z phase is confirmed.

In addition, please allocate the HOME sensor to latch compensation terminal SI5.. 1) Set Type_Code to logical rising edge of HOME sensor (012h) and set Homing_Ctrl bit to 0, and change normal command (20h) to return-to-home command (24h). Hold the return-to-home command (24h) until the return-to-home operation completes. 2) Execute the positioning (at 1st velocity) according to command position, which is based on the position at power-up. 3) When the logical falling edge of HOME sensor is detected (check HOME bit of the response), stop positioning and set Homing_Ctrl bit to 1. Then, reverse the rotation (2nd speed). 4) When the servo driver detects the logical rising edge of HOME sensor, set Homing_Complete bit to 1 and execute servo-lock at home position by ignoring command position. However, please keep in mind that the value becomes effective with as also during the servo-lock after cyclic homing operation when feedforward enters from the master (host controller). When this poses a problem, please set feedforward value as 0 during cyclic homing operation. 5) After confirming that Homing_Complete bit has become 1, set Homing_Ctrl bit to 0, and then set 0 (home position) to command position. 6) Change the command code to the normal command (20h). Then, positioning will start according to the new reference. Therefore, be sure to perform step 5) before changing the command code back to the normal command.

(It is internal operation value of the servo driver.) *2) Set up the 2nd Velocity as slow as possible. Noise filtering process in the servo driver is executed when capturing sensor signals. This process causes the detection delay. To minimize this delay, correction process is installed which will degrade the home position detection precision if 2nd speed is set too high. If you need higher accuracy, use the method of using the Z-phase of feedback scale, and refer to “Example of cyclic homing operation 1” on the previous page. When the trigger position is detected at a higher speed, especially with excessively low electronic gear ratio, e.g. 1/1000, wraparound of the detection position will occur upon reverse conversion to command unit, causing incorrect detection of the latch position. Latch trigger signal should be detected at the lowest possible speed.

Hold the return-to-home command until the homing process completes. 2) Execute the positioning according to command position, which is based on the position at power-up. 3) When the servo driver detects Z-phase of feedback scale, it will ignore command position and stop the motor (servo-lock) at detected home position (Z-phase). Then it will set Homing_Complete bit to 1. Note that during feedforward the value remains valid. If this causes a problem, keep feedforward value at 0 during homing process. 4) After confirming that Homing_Complete bit has become 1, set Homing_Ctrl bit to 0, and then set 0 (home position) to command position. 5) Change the command code back to normal command (20h). Then, positioning will start according to the new reference. Therefore, be sure to perform step 4) before changing the command code back to the normal command.

Note: For setting the thrust limit value, see section 4-5-3. 2) Execute the positioning according to command position, which is based on the position at power-up. At this time, lower Command Velocity for safety. 3) Actual velocity will be 0 when the slider hit the stopper, and the status will show the thrust limited (thrust limited bit will be 1). 4) After verifying that the thrust limited status continued for specified period (t1), switch the command from normal (20h) to return-to-home command (24h). Set Type_Code to actual position set (021h) and setting position (Byte 12–15) to 0 (or desired value). Do not change the command position. 5) When the process of actual position set has completed in the servo driver, the driver will ignore the value of command position and stop the motor (servo-lock) at the setup position. Then it will set homing complete bit to 1. Note that during feedforward the value remains valid. If this causes a problem, keep feedforward value at 0 during homing process. 6) After confirming that homing complete bit has become 1, then set the command position to the set actual position. 7) Change the command code back to normal command (20h). Then, positioning will start according to the new reference. Therefore, be sure to perform step 6) before changing the command code back to the normal command. 8) Bring the thrust limit value to the previous value.

When the position loop is configured on the host controller, set Pr.3.12, Pr.3.13 and Pr.3.14 to 0. When stop the operation with profile position control, set deceleration to Pr.8.04 (Profile linear deceleration constant) before starting operation. 2) On the host controller set command code to CV control normal command (30h) and set command velocity (CSPD). 3) On the servo driver, change control mode from position control to velocity control as the command code 10h changes to 30h, to accelerate (start operation) to command velocity (CSPD). 4) On the host controller, check that command code echo is 30h, no command error has occurred, and velocity control has started. If command error has occurred, start proper counter measure according to the error code. 5) When command velocity (CSPD) is changed during operation, the servo driver updates the velocity upon receiving the command. If the new command velocity (CSPD) is higher than the current command velocity, acceleration is made based on Pr.3.12, and if the new command velocity is lower than the current velocity, deceleration is made based on Pr.3.13. 6) To start stopping sequence, set the command velocity (CSPD) to 0. To use profile position control during stop sequence, set command code to 17h and Hard_Stop to 1 for immediate stop, or set Smooth_Stop or Pause to 1 to start deceleration according to Pr.8.04 setting. 7) When profile position control is used for stopping sequence: after completion of output of movement command, status In_Progress becomes 0 (transfer complete), and absolute value of position deviation becomes below Pr.4.31 (Positioning complete range), servo driver sets In_Position to 1 and informs the host controller that positioning has been completed.

If a command error has occurred, take appropriate countermeasure according to the error code. 5) Upon receiving new command thrust (TRQ) during operation, servo driver updates the thrust. 6) To trigger stop sequence, set command velocity (CSPD) to 0. To stop with profile position control, set command code to 17; to stop immediately, set Hard_Stop to 1; to decelerate according to the setting of Pr.8.04, set Smooth_Stop or Pause to 1. 7) When stopping under profile position control, the servo driver sets In_Position to 1 as status In_Progress is set to 0 (transfer complete) and absolute position deviation is below the value specified by Pr.4.31 (Positioning complete range), and informs the host controller that the positioning operation has completed. Precautions • While the velocity limit is active, the command thrust (CTRQ) from the host controller is not directly applied to the motor. As the motor velocity is controlled to the velocity limit value, the result is reflected on the thrust command to the motor. For velocity control function, refer to 4-2-3-4. R2.0 • While the thrust control is active, thrust limit switching function is disabled and only Pr.0.13 (1st thrust limit) is valid. • When absolute value of command thrust (CTRQ) exceeds the value of Pr.0.13 (1st thrust limit), Pr.0.13 is given priority.

This does not directly trigger profile operation. Before operating, set acceleration/deceleration through Pr.8.01 (Profile linear acceleration constant)/Pr.8.04 (Profile linear deceleration constant). 2) With command code 10h, set Type_Code to 10h, target position (TPOS) and target speed (TSPD). Set the target position as absolute position. Select data to be returned to Monitor_Data in Latch_Sel1 0 and Monitor_Sel. This does not directly trigger profile operation. 3) Change command code from 10h to 17h. 4) The servo driver starts the profile operation as the command code is changed from 10h to 17h, starting acceleration (starting operation) to the target velocity (TSPD). 5) On the host controller check that command echo is 17h, Type_Code echo is 10h and status In_Progress is 1, and no command error has occurred and absolute positioning has started. If command error has occurred, take proper counter measure according to the error code. 6) When changing the target position (TPOS)/target speed (TSPD) during operation, follow the procedure shown below. Pr.7.23, bit 5 = 0: start as reference command changes With command code 10h, change the target position (TPOS)/target speed (TSPD) value, and return to step 3). Pr.7.23, bit 5 = 1: start as command code and command argument change With command code 17h, change the target position (TPOS)/target speed (TSPD) value. If the new target position (TPOS) is near than the current internal command position (before filtering: IPOS), decelerate and stop according to Pr.8.04 and then accelerate to the new target position (TPOS). If the new target speed (TSPD) is larger than the current command speed, accelerate according to Pr.8.01, and if TSPD is smaller than the current command speed, decelerate according to Pr.8.04. 7) Then decelerate toward the target position (TPOS) at the rate set by Pr.8.04. 8) When the distance from internal command position (IPOS) to the target position becomes shorter than Pr.8.16 Profile positioning neighborhood range, NEAR becomes 1 (profile positioning neighborhood). After outputting movement to target position command, the servo driver sets status In_Progress to 0 (transfer complete). As the absolute value of position deviation decreases below Pr.4.31 (Positioning complete range), the driver sets In_Position to 1 and informs the host controller that the positioning has completed. Precautions • Other non-cyclic commands except for certain homing commands may be executed during operation (In_Progress = 1) while maintaining profile operation. However, do not change the operation mode (Type_Code, Latch_Sel1 of profile command), otherwise, Err91.1 (RTEX command error protection) and command error (0104h) will occur. • R2.0 If target speed (TSPD) is set at 0 or if Pause is set at 1, In_Progress will not be set to 0 (Internal position command stop) after deceleration and stop.

To minimize the error rate, lower the speed around latch signal input as low as possible. • Be sure to maintain the value of the latch signal (Latch_Sel1) while processing this command (latch detection process). • If the target position is reached without detection of latch signal, latch status will be held. Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 132 7-5-5 Profile position latch relative positioning (Type_Code: 13h) Specify the relative movement distance to TPOS and the servo driver performs positioning by internally generating position command. During positioning, it updates the target position upon detecting latch signal. To prevent movement to unintentional position, read command position (before filtering: IPOS) from the servo driver while pausing internal command generation (In_Progress = 0) in the PP control mode. Note: The internal command position (IPOS) will vary with the motor position during servo off, velocity control (CV) and thrust control (CT). This positioning differs from the profile position latch absolute positioning in Type_Code at starting and in specifying method of target position (TPOS). For details of operation of the profile position latch absolute positioning, refer to 7-5-4.

This does not directly trigger profile operation. Before operating, set acceleration/deceleration through Pr.8.01 (Profile linear acceleration constant)/Pr.8.04 (Profile linear deceleration constant). 2) With command code 10h, set Type_Code to 20h and target speed (TSPD). Set the target position (TPOS) to 0 because it is not used. Set 0 to Latch_Sel1, select data to be returned to Monitor_Data in Monitor_Sel. This does not directly trigger profile operation. 3) Change command code from 10h to 17h. 4) The servo driver starts the profile operation as the command code is changed from 10h to 17h, starting acceleration (starting operation) to the target velocity (TSPD). 5) The host controller checks that command echo is 17h, Type_Code echo is 20h and status In_Progress is 1, and no command error has occurred and absolute positioning has started. If command error has occurred, take proper counter measure according to the error code. 6) When changing the target speed (TSPD), follow the procedure shown below. Pr.7.23, bit 5 = 0: start as reference command changes With command code 10h, change the value of target speed (TSPD), and return to step 3). Pr.7.23, bit 5 = 1: start as command code and command argument change With command code 17h, change the value of target speed (TSPD). If the new target speed (TSPD) is larger than the current command speed, accelerate it according to Pr.8.01, or if new TSPD is smaller, decelerate it according to Pr.8.04. 7) To stop immediately, set Hard_Stop to 1; to decelerate according to setting of Pr.8.04, set Smooth_Stop or Pause to 1. 8) While operating in profile continuous movement (JOG) mode, NEAR remains 0 because no target position is set. After outputting the movement command, the servo driver sets In_Progress to 0 (transfer complete), and as the absolute value of position deviation decreases below Pr.4.31 (Positioning complete range), the driver sets In_Position to 1 and informs the host controller that the positioning has completed. Precautions • Other non-cyclic commands (e.g. monitor command) may be executed during operation (In_Progress = 1) while maintaining profile operation. However, do not change the operation mode (Type_Code, Latch_Sel1 of profile command), otherwise, Err91.1 (RTEX command error protection) and command error (0104h) will occur. • R2.0 If target speed (TSPD) is set at 0 or if Pause is set at 1, In_Progress will not be set to 0 (Internal position command stop) after deceleration and stop. To end the process during operation, transmit Hard_Stop or Smooth_Stop, then, In_Progress will be set to 0 (transfer complete) at stop. Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 135 7-5-7 Profile homing 1 (HOME + Z phase) (Type_Code: 31h) This return-to-home process uses Z phase from HOME sensor as the trigger signal. In this system, the position of the first Z phase after the HOME sensor in homing direction detected the rising edge is denoted as the home position. As the unit stops at the home position, the position information is initialized so that the position is set to 0. Direction of homing (positive/negative) can be set according to Pr.8.12 (Profile homing mode setting). Example: Pr.8.12 = 0 (Homing direction = positive direction trigger signal detection) Start area Homing direction (positive direction) NOT ON HOME ON POT ON Z phase Velocity 1 Velocity 2 Velocity 2 Velocity 1 Ex.

This does not start the profile operation. Parameters related to acceleration/deceleration (Pr.8.01/Pr.8.04) and homing (Pr.8.12Pr.8.14) should be set before starting operation. 2) With normal command (10h) condition, set Type_Code to 31h. Set target position (TPOS) and target speed (TSPD) to 0 because they are not used. Set Latch_Sel1 to 0. For Monitor_Sel, select data to be returned to Monitor_Data. This does not directly start profile operation. 3) Change command code 10h to 17h. 4) The servo driver starts profile operation as command code 10h changes to 17h, accelerates operation (starts operation) according to Pr.8.01 Profile linear acceleration constant to reach Pr.8.13 (Profile homing velocity 1). Note that upon starting the profile operation, Homing_Complete is set to 0. 5) The host controller checks that command code echo is 17h, Type_Code echo is 31h and status In_Progress is 1, and no command error has been generated, and homing operation has started. If command error is detected, the controller should take appropriate countermeasure according to the error code. 6) When POT is detected before HOME sensor detection, start deceleration according to Pr.8.04 to stop. 7) At the stop position, start movement in the direction opposite to the homing at the speed specified by Pr.8.13. 8) When HOME sensor turns on and then OFF edge is detected, start deceleration at the rate specified by Pr.8.04. 9) At the stop position, start movement in the homing direction, accelerating according to Pr.8.14 (Profile homing velocity 2), re-entering HOME sensor area and stop upon detecting the 1st Z phase. ▪ Actually, detected position is determined by repositioning. 10) Initialize the position information so that the detected Z phase becomes 0 and Homing_Complete becomes 1, and profile homing is finished. Precautions • If Z phase is close to a point where HOME changes, the 1st Z phase may not be detected as home due to reading delay of HOME sensor. Place Z phase far away from the point where HOME sensor changes the output. R2.0 • Sensors (HOME, POT, NOT) should be so arranged that once they detect something, nothing will pass through them until deceleration and stop complete. • During profile homing 1 (HOME + Z phase), Pr.5.04 (Over-travel inhibit input setup) and Pr.5.05 (Sequence at over-travel inhibit) are temporarily disabled. When POT/NOT is detected, reverse operation will automatically start after deceleration and stop. When using this function without using the over-travel inhibit input, do not allocate POT/NOT to general purpose input. Simply setting Pr.5.04 to 1 will not disable the function. • If an error occurs during homing, e.g. the sensor cannot detect the home during reverse operation due to the over-travel inhibit input and detects the over-travel inhibit input ON of reverse side, or, if both of over-travel inhibit inputs are ON state, Err94.2 (Homing error protection) will occur, canceling homing process. • Other non-cyclic commands except for homing commands may be executed during operation (until Homing_Ccomplete becomes 1) while maintaining profile operation. However, do not change the operation mode (Type_Code, Latch_Sel1 of profile command), otherwise, Err91.1 (RTEX command error protection) and command error (0104h) will occur.

Type_Code Description 32h When the detected POT/NOT and the direction of homing are the same direction, Err94.2 (Homing error protection) will occur and cancel homing process. 34h When the detected POT/NOT and the direction of homing are the same direction, reverse operation will automatically start after deceleration and stop. Home position is defined as the point where HOME sensor detects the rising edge in return-to-home direction. After stopping at the home position, initialize the position information so that this position is set at 0. Only positive homing direction is supported. Be aware that negative direction is not supported. Set Pr.8.12 (Profile homing mode setting) to 0. Setting Pr.8.12 to 1 also causes homing in positive direction.

Precautions for profile position control operation • When relative displacement exceeds 7FFFFFFFh (command unit), wraparound process is used. <Example of wraparound process: As TPOS changes from 7FFFFFFFh to 80000000h> Servo internal arithmetic command position (command unit) No relative movement by 4294967295 (command unit) in negative direction 80000000h 7FFFFFFFh Relative movement by 1 (command unit) in positive direction (wraparound process) 80000000h Physical position • When the latch trigger signal is applied from external source, it should be detected at the lowest possible speed. If it is detected at a higher speed, with very low electronic gear ratio (e.g. 1/1000), wraparound of detection position will occur upon reverse conversion to command unit (latch position is not exactly detected). • When the target speed (TSPD) is set outside the range, it causes command error (0032h). Maximum target speed will be the maximum overspeed level or 7FFFFFFFh (command unit/s), whichever small. Note: Maximum overspeed level includes errors caused by rounding in calculating process and by electronic gear. • During acceleration, deceleration will be started if continuous acceleration may cause movement beyond the target position. As a result, the speed may not reach the target speed (TSPD). • When deceleration is made to the target speed which is slower than the current internal command speed, and even if the resulting speed difference is smaller than the difference between decelerations, deceleration is made according to the new decoration rate and then acceleration will made to attain the target speed. If this process causes problem, take corrective measure, e.g. decrease Pr.8.04 (profile linear deceleration constant). R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 143 • The speed (including initial speed upon changing control mode) at the start of deceleration and Pr.8.04 (Profile linear deceleration constant) shall meet the following restriction. <Restriction> Amount of movement distance (P) necessary to decelerate from the initial speed to the target speed < 7FFFFFFFh (command unit) For example, if the initial speed upon switching from the cyclic thrust control does not meet the restriction, Err.27.5 (command generation error protection) will be generated.

MINAS-A5N can response to the new control mode changed during operation. For precautions for mode change during operation, refer to 7-6-2 and for other precautions refer to 7-6-3. • The non-cyclic command just prior to command mode change must be “Normal command (0h)”, and be sure to change the control mode while “Non-cyclic command” is not being executed (Busy = 0). If the control mode is changed while non-cyclic command is being executed (Busy = 1), Err91.1 (RTEX command error protection) and command error (002Eh) will occur.

Upon switching to PP during operation, the profile operation should be started: change to 17h and not to 10h. Switching from CP (cyclic position control) to PP, CV or CT is possible during operation. In contrast, switching to CP is possible while operation is paused. To smoothly change control mode to CP, when applying the command from the host controller, command position (TPOS) should include correction process. When changing from PP to CP, control mode remains position control, but correction is required to command position (TPOS) of given command. <Supported switching during operation> After switching Before switching PP (17h) PP(10h) ▪ CP (2h) CV (3h) CT (4h) CP(20h) CV(30h) CT(40h) Do not change control mode during the following PP operation. Otherwise, Err91.1 (RTEX command error protection) and command error (002Eh) will occur. Type_Code 12h 2.0 Operation mode Profile position latch absolute positioning 13h Profile position latch relative positioning 31h Profile homing 1 32h Profile homing 2 33h Profile homing 3 34h Profile homing 4 35h Profile homing 5 2.0 • When changing control mode during operation, correctly apply the command so that the velocity in the previous and new modes are the same. Actual velocity (APOS) before mode change = command velocity (target velocity) after mode change When control mode is changed during acceleration/deceleration, mode may not be smoothly changed. Even at the constant velocity, mode may not be smoothly changed due to certain factor, e.g. if acceleration/deceleration setting is large. • Before changing mode from CV or CT to PP with position command filter (FIR, smoothing) enabled, a steady constant velocity should have been maintained for a period longer than the filter time constant (FIR, smoothing total setting time). • For smooth switching between control modes, disable the damping filter because the damping filter is active only for position control. • When the gain changes after switching of control mode, switching is not smoothly performed. There are some other conditions that prevent smooth switching operation. If the vibration during switching cause problem, perform switching while related sections are in stop condition. R2.0 Motor Business Division, Appliances Company, Panasonic Corporation No. SX-DSV02310 - 146 7-6-3 Other precautions related to control mode switching • After servo-off (including alarm state), counter clear or deceleration and stop according to drive inhibit input, the control mode in the servo driver is forced to change to PP and internal position command generation process is forced to stop. For example, if the main power is turned off in CV status, servo is turned off and internal status is switched to PP. Result: status and monitor data that rely on control mode will be switched to position control instead of velocity control. 2.0 R2.0 • When command is NOP (0h), or if cyclic command is not correctly received due to command error or communication error, the previous command mode will be maintained. Note that commands (command velocity etc.) to servo driver will not be disabled. For NOP command, refer to 7-1-2, for command error, refer to 6-10, and for communication error, refer to 6-11. • When communication cycle is 0.0833 ms or 0.1666 ms, generation of response data (e.g. position deviation) depending on control mode will delay. For details, refer to 3-1-3 and 3-1-4. • For communication cycle/command update cycle, 16-byte mode/32-byte mode and combination of compatible control modes, refer to 2-5-1. If unsupported combination is selected, it will cause Err91.1 (RTEX command error protection) and command error (002Eh). • When selecting another control mode (cyclic command), wait for at least 2 ms. When several control modes are repeatedly switched within 2 ms, Err91.1 (RTEX command error protection) and command error (002Eh) will occur. • When homing command (4h) except for latch mode is being executed, do not change control mode. Before changing control mode, be sure to perform homing process and select the normal command (0h). Follow the basic switching method described above. • When Block Diagram of 2 Degrees of Freedom Mode is disabled,. do not change control mode other than position control mode. When control modes were changed, Err91.1 (RTEX command error protection) and command error (002Eh) will occur.
