Product Description
The Mitsubishi MELSERVO MR-J3-22KBS4 is a high-performance servo amplifier designed for precision applications, operating on 380-480VAC and delivering 22kW of power. Featuring extensive I/O (4 digital inputs, 2 digital outputs, 1 relay output, and 2 analog outputs), it supports 63A output current, consumes 45W, and draws 47.6A input current. Utilizing sine wave PWM and current control with forced ventilation cooling, it operates between 0-55C and stores between -20-65C. Its compact dimensions (400 x 260 x 260 mm) and compatibility with HA-LP series servo motors make it suitable for diverse automation and motion control applications with 50-60Hz input frequency.
Is Your Device Showing These Signs?
The Mitsubishi MR-J3-22KBS4 servo amplifier commonly experiences issues related to overcurrent faults stemming from shorted motor windings or damaged power transistors. Regenerative errors arise from excessive deceleration or high inertia loads, often requiring adjustment of deceleration parameters or external braking resistors. Communication failures are traced to faulty CN1 connectors, corrupted firmware, or incompatible network settings. Overheating results from inadequate cooling, excessive ambient temperatures, or a malfunctioning heatsink fan, demanding improved ventilation or fan replacement. Parameter corruption leads to erratic motor behavior, necessitating parameter verification and restoration from backup.

Our Repair Process for the
MR-J3-22KBS4
Our repair process for the Mitsubishi MR-J3-22KBS4 servo amplifier begins with a thorough diagnostic evaluation to pinpoint the root cause of the failure. Overcurrent faults are addressed by inspecting motor windings for shorts and replacing damaged power transistors. Regenerative errors necessitate adjustments to deceleration parameters or the installation of external braking resistors. Communication failures are resolved by repairing or replacing faulty CN1 connectors, reflashing corrupted firmware, or correcting incompatible network settings. Overheating issues are mitigated by improving ventilation or replacing malfunctioning heatsink fans. Parameter corruption requires verification against known good values and restoration from a verified backup.
