Mitsubishi MR-J4-40A-RJ: MELSERVO-J4 AC servo amplifier, 400 W, General-purpose interface interface, supply 1PHASE 230V, 3PHASE 230V. 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.
Servo amplifiers are set up with Mitsubishi MR Configurator2. Save the parameters of the old unit if possible; after replacement the parameters are written back and the motor runs as before.
