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.

IRMCS2031 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
