Description
IRMCS2031 is a complete sensorless drive design platform for industrial/appliance applications up to 1.0 HP output power.
The system contains the latest advanced motion control IC, IRMCK203, and the ServoDesignerTM software. The complete
B/Ms and schematics are provided so that the user can adapt and tailor the design per application needs. The system does
not requires any software code development due to unique Motion Control Engine implemented in the IRMCK203 IC. User
can readily evaluate high performance sensorless control without spending development effort usually required in the
traditional DSP or microcontroller based system. IRMCS2031 contains advanced iMOTION chipset such as IR2175 monolithic
current sensing ICs and IRAMX16A60A intelligent power module, which enable simple and cost effective motion control
design.

Overview
The IRMCS2031 is a design platform for a complete Sensorless drive system based on the IRMCK201 digital motion
control IC. The system is based on configurable control engine implemented by hardware logics in the IRMCK203.
The system has a simple and low cost structure, made possible by an advanced IR motion components including the
IRAMX16UP60A IGBT module, and IR2175 monolithic current sensing high voltage IC. These components together
with the IRMCK203 simplify hardware implementation. Since all control logic is implemented in hardware logic as
opposed to programmed software, unmatched parallel computation is achieved resulting in higher bandwidth control
and higher motor operating frequency (15 usec minimum PWM loop cycle).
Despite of hardware logic implementation, its design flexibility allows the user to configure Permanent Magnetic ac
motors (Sinusoidal Back EMF) with different motor parameters and different types of communication protocols.

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 IRMCS2031 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 LEDs is not an indication that capacitors have discharged to safe voltage
levels.
ATTENTION: The IRMCS2031 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 LEDs 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.
ATTENTION: The IRMCS2031 system contains ESD (Electrostatic Discharge) sensitive
parts and assemblies. Static control precautions are required when installing, testing,
servicing or repairing this assembly. Component damage may result if ESD control

procedures are not followed. If you are not familiar with static control procedures, reference applicable ESD
protection handbook and guideline.
ATTENTION: An incorrectly applied or installed drive can result in component damage or
reduction in product life. Wiring or application errors such as undersizing the motor, supplying
an incorrect or inadequate AC supply, or excessive ambient temperatures may result in system
malfunction.
!
!
!
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.

Debris When Unpacking
The IRMCS2031 system is shipped with packing materials that need to be removed prior to installation.
!
ATTENTION: Failure to remove all debris and packing materials, which are unnecessary
for system installation, may result in overheating or abnormal operating condition.

Installing the Software
The ServoDesignerTM tool is distributed on the CD-ROM. Load the CD into the CD-ROM drive on your PC and
double-click “IRMCS2031.exe”. It requires the password which also can be found in the same CD-ROM. The
automated procedure installs all necessary software on your PC. The default location for the installation is
“C:\Program Files\Accelerator”.
Power-On the System
Apply AC115V – AC230Vpower to the system.
Immediately after power-on, the power supply RED LED (located at the bottom left corner of the board) will light
indicating the on-board DC bus has been established. The second LED (surface mount LED located at the top side of
the board) should also start blinking on/off RED.
Getting Started
For quick start with preconfigured parameters, the following motor is supported with a preconfigured motor file.
•
Sanyo Denki motor (400W: type P30B06040DXS00M)
If any other motor is used, reconfiguration is required. Configurable parameters are required to tailor design to various
applications (motor and load). These configurable parameters can be modified via the host register interface (using the
ServoDesigner tool) through the communication interface. In the IRMCS2031 product, a design spreadsheet (Drive
parameters translator) is provided to aid the user for ease of drive start-up. Using the spreadsheet, the user enters
high-level parameters such as motor nameplate information, maximum application speed, current limit, speed and
current regulator bandwidth. This high-level user information is translated to engineering parameters (directly used
by the drive). Figure gives an overview of the commissioning steps. Please refer to the IRMCK203 Application
Developer’s Guide for detailed drive commissioning description.

Shunt Resistor and Current Rating
Two 20m Ohms current sensing shunt resistors are equipped as default resistors at factory shipment (R34 and R36
located on the bottom side of PCB). With these resistors, IRMCS2031 can deliver up to ±13A maximum peak
current to the motor including overshoot of current regulation.
When using any higher power motor with a rating greater than 3Arms and less than 6Arms continuous current, then
10m Ohm shunt resistors are recommended in place of the 20m Ohm shunt resistors.

RS-232 Register Access
The IRMCK203 includes an RS-232 interface channel that provides a direct connection to the host PC. The software
interface combines a basic "register map" control interface with a simple communication protocol to accommodate
potential communication errors. For more detailed information, please refer to IRMCx201 Application Development

RS-232 Register Write Access
A Register write operation consists of a command/address byte, byte count, register data and checksum. When the
IRMCK203 receives the register data, it validates the checksum, writes the register data, and transmits and
acknowledgement to the host.
