1. Overview

The IRMCS2013 is a low voltage 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 IR2106 gate drive high voltage IC, 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 IRMCS2013 system block diagram. Since all control logic is implemented in hardware

logic as opposed to software program, 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

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 IRMCS2013

schematics and B/Ms.
