Description
IRACS201 is a complete servo drive design platform for
AC servo drive applications up to 1.5kW. The system
contains complete hardware and preloaded object code
for the FPGA, and the GUI (graphic user interface)
software. Complete hardware schematics and B/Ms are
provided so that user can adapt design into specific
needs. IRACO201 downloadable object code is also
available for volume usage of IRACS201 design. User can
evaluate high performance servo drive with a specific
motor, and tailor the drive design
