Description
IRMCO201 is an FPGA object code for a complete AC servo control system, which can be downloaded into the Xilinx Spartan2-
300^TM low cost FPGA. With IRMCO201, the user can readily build a high performance servo drive system without any
programming effort. IRMCO201 provides an immediate solution for high performance AC servo amplifier applications. This soft
ASIC is so flexible that the user can configure and optimize the system specifically to the needs of each application. With
International Rectifier high voltage ICs such as IR2175 current sensing IC and IR2137 3-phase gate drive IC, IRMCO201
minimizes the analog and power electronics component count, and simplifies the design for low cost AC servo solutions.
