IRMCS2011
1. Overview
The IRMCS2011 is a design platform for a complete servo drive system based on IRMCK201 IC. The system is based
on configurable Motion Control Engine implemented by hardware logics in the IRMCK201. The system has a simple
and low cost yet very flexible structure, made possible by advanced IR motion components including the
IRAMX16UP60A IGBT module, and IR2175 monolithic current sensing high voltage IC. These components together
with IRMCK201 IC simplify hardware construction, and perform complete servo amplifier functions. Figure 1 shows
the IRMCS2011 system block diagram. Since all control logic is implemented in hardware logic as opposed to
programmed software, unmatched parallel computation is achieved resulting in high bandwidth torque control.
Despite the fact that technology is based on hardware logic implementation, its design flexibility allows the user to
configure different types of motors, position feedback devices, and communication protocols. The system also allows
feedforward control in addition to existing PI control.
Design cycle time can be greatly shortened. Unlike a traditional DSP or microcontroller, the architecture is based on
configurable register interface, and does not require any programming to complete customization for specific
application needs. The user only has to configure the drive using ServoDesignerTM interactive design tool and it takes
just a matter of hours instead of months and years.
Once the user become satisfied with function and performance, he can generate his own design using IRMCS2011
schematics and B/Ms.

2. Getting Started
2.1 Safety Precautions
In addition to the precautions listed throughout this manual, you must read and understand the following statements
regarding hazards associated with AC servo development system.
!
ATTENTION: Some ground potential of the IRMCS2011 system is biased to a negative
DC bus voltage potential and kept high voltage potential while power is on. When measuring
voltage waveform by oscilloscope, the scope ground needs to be isolated. Failure to do so
may result in personal injury or death.
Darkened display LED is not an indication that capacitors have discharged to safe voltage
levels.
!
ATTENTION: The IRMCS2011 system contains high voltage capacitors which take time to
discharge after removal of main supply. Before working on drive system, ensure isolation of
mains supply from line inputs [R, S, T]. Wait three minutes for capacitors to discharge to
safe voltage levels. Failure to do so may result in personal injury or death.
Darkened display LED is not an indication that capacitors have discharged to safe voltage
levels.
!
!
ATTENTION: Only personnel familiar with the drive and associated machinery should
plan or implement the installation, start-up, and subsequent maintenance of the system.
Failure to comply may result in personal injury and/or equipment damage.
ATTENTION: The surface temperatures of the drive may become hot, which may cause
injury.

3.2 Assembling Encoder Connector
Prepare the connector assembly to the encoder cables.
• Assemble 15-pin male D-Sub connector, referring to Figure 2.
• Make sure that the encoder is a 5V type. If it is not a 5V type, proper modification is required.
For permanent magnet motors:
• Eleven pins are used: A+ (pin 2), A- (pin 3), B+ (pin 4), B- (pin 5), Z+ (pin 6), Z- (pin 7), HALL_A (pin 10),
HALL_B (pin 11), HALL_C (pin 12), 5V(pin 1 or pin 9) and GND (pin 8 or pin 15).
• If hall sensors have differential output, connect only positive sides and leave negative sides open.
For induction motors:
• Only six pins are used because z-pulse is not necessary for an induction machine. The six pins are: A+ (pin
2), A- (pin 3), B+ (pin 4), B- (pin 5), 5V(pin 1 or pin 9) and GND (pin 8 or pin 15).
• Disable Z_pulse by connecting Z+ to GND and Z- to 5V.

3.3 Motor Power Cable
Prepare the motor power cable, which has four wires: U, V, W and E (earth ground). Proper size and length of cable
should be used.
4. Hardware Installation
4.1 Safety Precautions
!
!
!
ATTENTION: Remove and lock out power from the drive before you disconnect or reconnect
wires or perform service. Wait three minutes after removing power to discharge the bus voltage.
Do not attempt to service the drive until bus voltage has discharged to zero. Failure to do so may
result in bodily injury or death.
ATTENTION: The drive is intended to be commanded by control input that will start and stop
the motor. A device that routinely disconnects then reapplies input power to the drive for the
purpose of starting and stopping the motor should not be used. Failure to follow this guideline
may result in damage of equipment, and/or bodily injury or death.
ATTENTION: Do not connect power factor correction capacitors to drive output terminals U,
V, and W. Failure to do so may result in equipment damage or bodily injury.

5. Software Installation
5.1 Installing from the CD
The distributed CD contains all necessary documents and software files. Load the CD into the CD-ROM drive on your
PC and double-click “IRMCS2011.exe”. It will ask you for a password, which is in the file “iMOTION Install
IRMCS2011.pdf”. After you enter the password, an automated procedure will install all necessary software on your
PC. The default location for the installation is “C:\Program Files\iMOTION”.
5.2 ServoDesigner Startup
You should follow the instructions in this section the first time you use ServoDesigner to verify your installation and
test the reference design. These “quick start” instructions assume that you’re using one of the supported motors
listed in section 3.1. If not, you’ll need to enter motor configuration parameters before you can begin testing. Refer to
“ServoDesigner User’s Guide” and “IRMCK201 Application Developer’s Guide” for more information.
Step 1. RS232 Connection
ServoDesigner communicates with the IRMCS2011 using a COM port on your PC. Before you start the application,
you should attach an RS232 cable to the DB9 connector on the reference platform and connect it to an available COM
port on your PC.
The first time you start ServoDesigner, a Connection dialog (shown in Figure 7) appears and presents you with a list of
available COM ports on your system. Select the COM port to which you have connected the RS232 cable.
Figure 7. The Connection Dialog
The Connection dialog also allows you to enable and disable product ID and version checking and status polling. You
should have “Product ID and version checking” disabled and “Status polling” enabled!
When you click OK in the Connection dialog, your selections are saved so they can be used next time you start the
application. (The dialog won’t appear on startup again.) If you want to change your selections later on, you can access
the Connection dialog through the Preferences menu.
The currently configured COM port is shown on the status bar at the bottom of ServoDesigner’s main display.
Step 2. Numeric Format
The first time you start ServoDesigner, the Numeric Display Format dialog appears, as shown in Figure 8. This dialog
allows you to select either decimal or hexadecimal format for numeric display. Click the blue button to switch between
hexadecimal and decimal. When you click OK, your setting is saved so it can be used next time you run
ServoDesigner. (The dialog won’t appear on startup again.) If you want to change the setting later on, you can
access the Numeric Display Format dialog through the Preferences menu.

6. Running the System
6.1 Power-On
Apply AC 115V – AC 230V power to the system. Immediately after power-on, the red LED (surface mount LED
located at the right side of the board) will lit on/off indicating the on-board DC bus has been established.
6.2 Running motor with ServoDesigner
Step 1. Opening the Configuration File
You need to open a configuration file. The configuration file contains the register, functional and monitor definitions
that make up ServoDesigner’s tree view. To start, you should open one of the default files that are shipped with the
release. Later, when you’ve modified the register values, function definitions and/or tunable parameters, you’ll want to
save your custom configuration in another file.
A default configuration file for each supported motor is shipped with the release. The file names include the part
number of your product and the part number of the motor, with the file extension “.irc”. For example, one of the
configuration files for the IRMCS2011 product is named “IRMCK201-GMB2010-17-E.irc”. The files are located in
the iMOTION\ServoDesigner directory. To open a configuration file, select Open from the File menu or click the
toolbar button that shows an open folder. Browse for the file you want and click OK. An example is shown in Figure
9.
Figure 9. Open a Configuration File
Note: Configuration files are saved in text format, but you should not edit the files manually. If you need to make
changes to a configuration file, open the file in ServoDesigner, make the changes as described later in this document,
and then save the changes by selecting Save or Save As… from the File menu.
Step 2. Checking Communication Status
Until you open a configuration file, the COM port status at the bottom of ServoDesigner’s main display shows
“Inactive”. When you open a file, ServoDesigner attempts to establish contact with the IRMCS2011 by executing a
read operation. If ServoDesigner receives a reply to its request, the COM port status shows “Up.” If no reply is
received, the status changes to “Down.” A “Down” status usually means the reference platform is not powered on, the
RS232 cable is not connected, or the cable is connected to the wrong COM port. Figure 10 shows how communication
status should appear before you continue your testing .

REFERENCE DESIGN
IRMCS2011
Figure 10. Communication Status Indicator
Note: If you disable status polling in the Connection dialog, ServoDesigner does not attempt to establish contact
with the reference platform, and the COM port status shows “Inactive” even after you open a configuration file.
Step 3. Motor Configuration
The Configure Motor function is one of the pre-defined operations in ServoDesigner’s Function Definitions section.
This function initializes the host registers for normal operation. If you click the Configure Motor entry in the tree
view, a list of the registers that are written when this operation is executed is displayed in the right pane of the main
window. The “Value to Write” column shows the value that will be written to each register. You can click the “+”
symbol to the left of the Configure Motor function to access detailed information about each of the registers.
To execute the Configure Motor function, click the Configure Motor toolbar button (the icon shows a hammer
and wrench) or double-click on the Configure Motor entry in the tree view.
Once this function is executed correctly, the LED will turn to blinking green.
Step 4. Starting Angle
For induction motor operation, skip this step. This function reads the Hall A, B, C inputs and uses the motor magnet
position data read from your configuration file to determine the starting position of the motor. (See “ServoDesinger
User’s Guide” for more information about motor configuration parameters.)
To execute the function, click the Starting Angle toolbar button (the icon shows the characters “ABC”) or
double-click the Starting Angle entry in the tree view.
Step 5. Running the Motor
Start Motor and Stop Motor functions are also pre-defined Function Definitions.
To start the motor, click the Start Motor toolbar button (the green traffic signal) or double-click the Start Motor
entry in the tree view.
To stop the motor, click the Stop Motor toolbar button (the red traffic signal) or double-click the Stop Motor
entry in the tree view.
When the motor is running, the far right hand status bar pane should show drive status “Run” with a green indicator.
When the motor is stopped, the drive status should be “Stop” with a yellow indicator. If a drive fault occurs, the
status changes to “Fault” with a red indicator. The status is “Inactive” (blue indicator) when the COM port status is
“Down” or “Inactive.”
Step 6. Reference Speed
ServoDesigner provides a special built-in function that allows you to easily control the motor’s reference speed and
direction. To modify the settings, see Figure 11. First, locate the Reference Speed entry in the Function Definitions
section of the tree view. Right-click on the entry and select Properties. In the Properties dialog, you can enter the
desired speed in RPM and the direction (forward or reverse). In the dialog, you can also specify the host register to
which the speed/direction setting is written. You should not modify this setting unless you redefine the host register
map.

14
REFERENCE DESIGN
IRMCS2011
After entering a speed and selecting forward or reverse, click OK in the dialog and then double-click the Reference
Speed entry in the tree view to execute the operation. ServoDesigner calculates the appropriate value to be written the
host register (based on your specified speed and direction) and performs the write operation.
Figure 11. Setup for Reference Speed Function
Step 7. Drive Status
The Info button on the toolbar (letter “i”) executes the pre-defined Drive Status function, which reads a group of host
registers associated with the function.
To get drive status, click the Info button or double-click the Drive Status entry in the tree view. After you’ve
executed the function, click on Drive Status in the tree view (if it’s not already selected). In the right pane of
the main window, the values read from the Drive Status registers are shown in the Current Value column.

7. Motion Control Engine
7.1 Motion Control Engine (MCE) Based Complete Servo Control
Figure 12 shows the detailed algorithm block diagram including various parameters which can be configured
through the host register interface.
Closed loop current and velocity control are implemented in the IRMCK201 IC on the IRMCS2011 board. The
closed loop current control algorithm is based on a synchronously rotating frame. The velocity control is available
as an outer loop control of the current control and can be disabled in order to configure torque control mode.
Additional configuration allows feedforward control, selection of the position feedback devices, induction machine
vector control, and selection of communication protocol.

8. New Motor Adaptation
New motor can be configured by simple EXCEL spreadsheet. EXCEL spreadsheet template is provided in the
shipment with the filename “IRMCx201-DriveParams.xls”.
This spreadsheet facilitates configuration of parameters which need to go into each host registers inside of the
IRMCK201 IC. The spreadsheet calculates current feedback/speed feedback scaling, Proportional plus Integral (PI)
gains of current and speed regulators, PWM carrier frequency, deadtime, etc, based on simple motor nameplate and
published data input. The output of this spreadsheet is text file containing one-to-one corresponding each registers’
values. User can use the ServoDesignerTM to read this output into the associated registers.
For detailed operation, please refer to “3.1 Drive Parameter Setup” in IRMCK201 Application Developer’s Guide.

Description
Figure 17 and Figure 18 show detailed timing requirements for register read and write operations depending on the
type of microprocessor (Intel or Motorola type). All values are in nanoseconds. The data bus output is activated by
the logical combination (!nCS && !nOE && new), which allows read and write operations to be either nWe/nOE
(Intel) or nCS (Motorola) driven.
