The system contains complete hardware and preloaded object code for the FPGA, and the ServoDesignerTM software. Complete hardware schematics and B/Ms are provided so that user can adapt design into specific needs. IRMCO201 downloadable object code is also available for volume usage of IRMCS201 design. User can evaluate high performance servo drive with a specific motor, and tailor the drive design This document is the property of International Rectifier and may not be copied or distributed without expressed consent. 57.6 kbps 8 kbyte
