1.2. SPA description and explanation
Mounting the spindle position display (SPA) is by docking hollow shaft onto spindle shaft (max.14 mm in diameter).The hollow shaft is fixed to the spindle shaft by hexagon screw and secured by power grip.
This way, the SPA is mounted in an overhung position and secured against torsion by torque support provided
at rear of the housing. The SPA features an absolute multiturn sensing system capable of detecting the position
after several spindle turns even in powerless state. Position data will be retained even in case of power failure
(min. 10 years).
The current position value is indicated in the two-line backlit LCD display (2x 5 digits, numeric), optionally together with the target transmitted by the control (master). Two arrows indicate the editing engineer the direction
the spindle must be turned to for aligning actual value with target. As soon as actual value is in alignment with
target and within the permitted tolerances, the target will disappear. By corresponding master parameterization
the display can be turned by 180° enabling vertical respectively horizontal installation. SPAs are networked by
M8 connector, power supply is by the same cable directly by master. SPA parameterization by master only.

1.3. Betriebsarten
Two operating modes are available to define the order of SPA alignment within the network.
Direct mode:
Interactive mode:
The master will enable the SPAs in successive order for the positioning operation.
The master will enable all SPAs respectively all SPAs in one group. The processing order
in the alignment operation must be defined by the operator.
a) Direct mode:
In „direct mode“ the master will transmit the motor start signal (command „D“) to a specific SPA which is first to
be aligned by power tool. The red status LED is flashing fast (at approx. 2 Hz) while the relevant IR positioning
data are being transmitted to the power tool. After the positioning operation the LED switches to green continuous what is recognized by the master when reading out the status flag (command „CX“ or „F“). Now the master
will transmit the motor start signal to the next SPA. This procedure will repeat until all SPAs have been aligned.
The order allows for individual alteration upon every profile change.
b) Interactive mode:
In „interactive mode“, the operator defines the order of SPA alignment.
Instead of transmitting the motor start signal (command „D“) to a specific SPA, the master will address all SPAs
in one group by broadcast command (address 99). The red status LEDs of all addressed SPAs is flashing slowly (at approx. 1 Hz). Now the SPAs are enabled for alignment but so far no positioning data have been transmitted to the power tool via the IR interface. The operator chooses one of the slowly flashing SPAs and pushes
one of its buttons. The red LED is now flashing rapidly (at approx 2 Hz) while this SPA is transmitting the IR
data. Once the aligning operation has been completed, the LED switches to green continuous. The operator
turns to the next SPA with a slowly flashing LED and will repeat the procedure until all SPAs have been aligned.
An already activated SPA (LED flashing fast) is set back to stand-by when pressing the button anew. The LED
is flashing slowly again and IR data transmission is aborted.
In group alignment operations, both modes can be combined. Example:
Firstly all Multicon AccuDrive devices are enabled for positioning by broadcast command, the order of alignment
is up to the operator .As soon as each SPA of group 1 is „in position“, the master will proceed with the next
group in direct mode.

* To avoid bus collisions a minimum timeout reply of 1 ms (default parameter)
is to be kept, i.e. the time elapsed between transmitting the last bit of the
query until start transmitting the 1st bit of the SPA response.
The operator should see that due to the minimized timeout reply of 1 ms
the bus switching time after having transmitted the last bit must not exceed
1 ms.
The default parameter of 1 ms can optionally be altered by serial interface
in steps of 0,1 ms within the range of 0,1 ... 60 ms. Refer to command „x“
(78h).
** The BUS switching time is the time the SPA requires to be ready again for
transmission receipt after having replied to host.

3.3. Checksum (Cyclic Redundancy Check)
For optimized error-free data transmission the CRC byte is added after the footer token (EOT, end of transmission) to the string to be transmitted. Upon receiving a command the CRC byte transmitted is crosschecked with
the auto-calculated CRC byte.
Algorithm:
1) Reset CRC byte.
2) Rotate CRC byte by 1 bit to the left.
3) Link result to first data byte XOR.
4) Rotate result by 1 bit to the left.
5) Link result to the second data byte XOR.
:
x) Rotate result by 1 bit to the left.
y) Link result to the last data byte (ever 04H) XOR.
z) Add result as CRC after the footer token (04H) to the string transmitted.

3.4. Data transmission properties
For reasons of compatibility, within the complete multicon system the amount of data is always the same (see
table in chapter 6), no matter how many digits are in the display. For example, command “R” (read actual value)
comprises a transmitted data amount of 6 bytes, but only 5 digits are indicated in the display. If it is a negative
value, digit 6 respectively digit 5 is always 0 (30h).
3.5. Broadcast commands
Some specific commands are designated so-called broadcast commands. As soon as the master broadcasts a
command to identifier 99, the command is addressed to every multicon device in the network. Each individual
SPA will accomplish the respective command but will not respond any confirmation to master.

N 153
3.6. Data saving
Specific parameters are saved in EEPROM (1.000.000 writing cycles). Data saving is via interface upon every
parameter transmission to SPA.
Important:
There should not be a cyclic transmission of these parameters to SPA but only if necessary, for example in
case of parameter alteration. The relevant parameters saved in EEPROM are listed in the charts in chapter
“Comand explanations” or “Overview on commands”.
3.7. Transmitting and reading negative values
The minus sign (2DHex) is always transmitted by digit 6 of the data field.
Example: Taking for granted a negative target of –1.5 and a programmed resolution of 1/10, the transmitted
value is –00015.
3.8. Transmitting and reading position values (decimal point)
Position values as for example target (command „S“), offset (command „U“) or end positions (command “g”) are
generally transmitted and read without decimal point. Visualization in the display corresponds to the format in
the data field of the interface command.
Thus, the transmission format depends on the resolution (see command „a“).
Example 1: resolution = 1/100; target = 278.50; actual value = 1.00

Target = 278.50

4.2.1. Check Position „C“ (43h)
This command provides the alignment status of target versus actual value. If the actual value is within the target
tolerance window, the response will be „o“ (6Fh) for OK together with the current profile number. If the actual
value is outside the tolerances, „x“ (78H) followed by the current profile number will be replied. In case of any
SPA error occurred, the response will be “e” together with the active profile number.

4.2.2. Motor start enable „D“ (44h)
This command is utilized to read the actual SPA enable status or to set respectively clear motor start enable.
The following modes are available:

3
:
Significance
(30h) abort motor start enable, motor stops
(31h) start enable SPAs of group 1
(32h) start enable SPAs of group 2
(33h) start enable SPAs of group 3
:
:
There are two separate options regarding start enable. First, every SPA can be started individually. The order is
determined by host and might also relate to SPAs of other groups. Start command “D” is transmitted to the respective device identifier including group number. The status LED is flashing rapidly, indicating that the SPA is
transmitting motor control data (see also examples 1 and 2).
Second, all SPAs of one group can be started at the same time by broadcast command (ID = 99). In this case,
the status LEDs of the SPAs belonging to the respective group are flashing at the frequency of 1 Hz, but the
SPAs have not yet been transmitting any motor control data. By key actuation the operator starts control data
transmission and now the status LED is flashing rapidly (see example 3). Upon another key actuation the control data transmission is deactivated what is visualized by the status LED flashing slowly.
Example 1: Read actual motor start enable status (status = 0 = disable)

Direct positioning „SD“
This command may be utilized for direct positioning operations. Only the target less any profile number is transmitted to SPA. The profile number after the command “S” is replaced by sub command “D” ( = dimension). Motor start enable requires transmitting in addtion motor start command “D”.

Transmitting targets with simultaneous motor start signal
Specific applications require autonomous re-alignment of shafts to the new target when it is received without
prior enable signal by command „D“. For this intention the following commands are available:
SPF transmits to SPA profile number together with motor start signal for automated positioning operations
SDF transmits to SPA position value together with motor start signal for automated positioning operations
The addressed SPA is enabled by adding sub-command „F“ to the respective basic command. Since it is a pure
individual positioning operation, defined groups are not affected. Collision prevention is up to the operator.

4.2.8. Set actual value as preset „Z“ (5Ah)
Command “Z” is utilized to set the actual value at any optional value. The required position value is transmitted
to the SPA. The SPA will calculate a so-called “preset offset” value relating to the true absolute encoder position. When calculating the preset offset, any programmed offset transmitted by command “U” will be considered,
so that after having accomplished command “Z” the current value always equals the preset.
Note: If the resolution is altered (see command “a”) from 1/100 to 1/10 or vice-versa, the previously programmed preset has to be set anew. The auto-calculated offset is provided in the previously selected resolution.
The actual value displayed is composed as follows:

Significance of parameter „a“
Positioning direction
This parameter defines the direction the target is aimed for. Tolerances that occur for example at cogwheels,
joints, shafts etc during a precise positioning operation requires a tolerance compensation. The tolerance compensation is proceeded by aiming for the target position always from the same direction utilizing so-called loops.
Loops mean that the target position is first crossed by a defined distance and then aimed for again from the opposite direction. The parameter for the crossing distance is programmed by command “b”. Whether a loop is required or not is indicated by the arrows in the display. A flashing arrow means tolerance compensation required.
Upon reaching the turning point the direction changes and the arrow stops flashing. Targets allowing direct positioning are marked by a non-flashing arrow. Upon achieving the target within the programmed tolerances (see
command “b”) the arrows will not disappear until the required tolerance compensation has been completed.
00 = Up
01 = Down
00 = Up
01 = Down
Counting mode
This parameter assigns either „ascending“ or „descending” counted values in relation to the shaft’s direction of
rotation. Following parameters are available:
00 = Up
01 = Down
Clockwise rotation, ascending counted values
Clockwise rotation, descending counted values
Arrows
This parameter relates to the arrows in the display that indicate the operator the direction (to the right or to the
left, up/down) of the new positioning operation. Following parameters are available:
00 = Up
01 = Down
10 = Uni
11 = Off
If actual value < target = arrow to the right; actual value > target = arrow to the left
As „Up“, but inverted arrows direction
If actual value ≠ target arrows ever indicated
Arrows ever hidden
Note: A loop operation (as backlash compensation) is only performed with settings Up and Down. Uni and Off
always implicate a direct movement to the target without backlash compensation.
Rounding the actual value
This means that the actual value being within the tolerances but still differing from the target is rounded up or
down to the target value as soon as the shaft remains idle for approx. 3 seconds. The rounding operation is only
visual, the true internal actual value remains unchanged. For actual value readout by serial interface (command
“R”) the true, not rounded actual position value is provided. The true actual value will immediately reappear on
the display upon actuating a key. If the position is still within the tolerance window the rounding operation will be
repeated after 3 seconds.
Note: In operating mode „Suppress target = Ever“ the target is deactivated and the SPA serves as pure actual
value display with disabled rounding function. The following parameters are available:
0 = Off
Round actual value disable
1 = On
Round actual value enable
Turn display
This parameter is utilized to turn the display by 180°.
0 = Off
1 = On
Display readout with standard mounting, i.e. display above keypad
Display readout with inverted mounting, i.e. display below keypad
Dimension
Only in conjunction with N 242 master. By this parameter the master enables indication of actual value and direct positioning (so-called dimension). Refer also to N 242 user manual.
Utilized with other controls (PLC or PC) this parameter may be assigned to general identifications.

Offset
Command „U“ is utilized for programming the offset that is added to actual value and actual target. This parameter defines whether the offset is considered in the calculation.
0 = Off
1 = On
Offset disabled. Any offset previously transmitted is NOT added neither to actual value nor
taget.
Offset enabled. Offset is added to actual value and actual target.
Suppress target
This parameter defines when to indicate the target in the upper line of the display.
0 = On
1 = Off
2 = Ever
Target indicated if target ≠ current value.
Target ever indicated, also if target = current value. Indicate arrows too if target ≠ current value.
Target and arrows ever suppressed.
Resolution
This parameter defines the resolution of the actual value. Upon altering the resolution the decimal point is
shifted correspondingly by one digit to the right or left, same applies also to actual value and target. The target
values however are not converted correspondingly but only the decimal point is shifted. When editing the machine please pay attention to defining the resolution first so that the target values are transmitted to the SPAs
with the corresponding resolution.

4.3.6. Read / write motor speed switching points „h“ (68h)
This command is utilized to read or write the motor speed switching points. Prior to reaching the target the motor speed can be slowed down for high-precise target positioning. Furthermore it is possible to set the motor
switch-off point at a designated value relating to the target. The following two parameters are defined:
Precision speed: point where SPA changes from high speed to precision speed.
Switch off point: Position where motor is stopped by SPA .
The individual switching points are indicated in relation to the target.

4.3.8. Read / write timeout at bus error RS485 „j“ (6Ah)
This command is utilized to read or write the system time: timeout at bus error. Value range is within 00,1 s to
99,9 s. Tolerance: ±7% at minimum time; < 1‰ at maximum time, approx. 1% at 1.
Function: RS485 bus monitoring during motive shaft positioning operations. If there is no interface activity within
the programmed timeout the motor will stop (EMERGENCY OFF) upon occurring a bus error or in case of an
inactive control. A motor restart requires transmitting the profile (command „S“ or „V“) together with the start
signal (command „D“). Setting 0.00 s means function disabled.

4.4.1. Assigning device identifiers in the network „A“ (41h)
This command is creating an automated process assigning the device identifier in successive order to every
single SPA upon commissioning of the system. The first identifier to be assigned is broadcasted to all networked SPAs as follows:

All SPAs now show the identifier just transmitted and that is to be assigned in the upper display. The bottom line
indicates the device-specific identifier.To make the SPA adopt the new identifier, the shaft must be turned by
half at least (direction does not matter). The identifier is now adopted and indicated in the bottom line of the display (as new device-specific identifier). Both identifiers are now identical. As soon as the shaft is in idle position
again and after having elapsed 3 seconds, the SPA will transmit the following command „B“ (42h) as confirmation to master:

The Master can now transmit command „A“ with the next identifier to be assigned as previously described.
This way, the different (successive) identifiers are automatically assigned to all networked SPAs, one after the
other.
Important: Confirmatory command „B“ transmitted by SPA to master will be repeated after 3 seconds provided
the master has not previously transmitted another „A“ command.
Indicate identifier in the display „A“ (41h)
This command less parameters as a broadcast command (address/Identifier=99) will make every networked
SPA indicate the device-specific identifier in the bottom line of the display. The upper line is blind.
This command is a designated broadcast command.

SPA will return to standard operating mode and reply the actual device identifier.

Similar to the standard command all SPAs now indicate the identifier just transmitted which is to be assigned in
the upper display. Adopting the identifier is in the same way. However, contrary to the above there is not any
acknowledgement „B“ in reply. Checking whether the new identifier has been adopted is up to master, for example utilizing command “R” (read actual value). The R-command with the corresponding identifier is transmitted to the SPA. If the addressed SPA confirms that the assignment was successful, the master can proceed
with next identifier. Regarding other commands the display of the respective SPA switches to standard operation.
