The Mitsubishi Electric MR-J4-10B-RJ is a MELSERVO-J4 servo amplifier rated 100 W, with sscnet iii/h command interface. 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.
