I. Product Overview

DF9201012-C0 (JANCD-MEW02-1) is an additional axis servo control board specifically designed by ABB for Motoman industrial robots. It is mainly used to expand the robot system, control external servo axes (such as transfer machines, flipping tables, walking axes, external manipulators), and achieve synchronous linkage, coordinated movement, and precise positioning between the robot and external equipment. It is widely used in welding, handling, assembly, cutting, etc. in automated production lines. C0 is a high-performance hardware revision.
