I. Product Overview

DF9201455-B0 is a 4-axis servo control board specifically for Yaskawa DX200/YRC1000 controllers. It is a hardware iteration improvement version of the A0 version (REV.B0).

It is mainly used for synchronous motion control of robot body servo drives and external auxiliary axes (tool changer, walking axis, flipping table), compared to the earlier A0 version, it optimizes FPGA logic, improves signal stability, enhances anti-interference and compatibility, and is compatible with welding, handling, assembly, stamping and other automated production lines.

II. Version and Compatibility (B0 vs A0)
