Rated 400 W, the Mitsubishi MR-J4-40B-RJ drives MELSERVO-J4 servo motors of the matching size in positioning and speed applications. When the replacement arrives, connect the same motor, encoder cable and I/O connectors, write back the parameters, and run a test at low speed before restarting production.
The amplifier must match the motor series and capacity; Mitsubishi publishes the allowed motor combinations in the servo amplifier instruction manual.
