Description

IRMCS2013 is a complete servo drive design platform for low voltage AC servo drive applications up to 350W. The system

contains the latest advanced motion control IC, IRMCK201, and the ServoDesigner

schematics are provided so that the user can adapt and tailor the design per application needs. The system does not require

any software code development due to unique Motion Control Engine implemented in the IRMCK201 IC. User can readily

evaluate high performance servo control without spending development effort usually required in the traditional DSP or

microcontroller based system. IRMCS2013 contains advanced iMOTION

sensing ICs and IR2106 gate drive ICs, which enable simple and cost effective motion control design.
