Product Description
The Mitsubishi MRH22KBN is a high-performance 22kW AC servo amplifier from the MELSERVO MR-H series, designed for 200-230VAC 3-phase power. It features absolute position detection with encoder and battery, operates in up to 90% humidity and 0-55C temperatures, and uses sine-wave PWM current control. This IP00-rated amplifier, with a 33kVA power supply capacity, includes overcurrent, overvoltage, and thermal overload protection, encoder error detection, and a minimum 250Hz speed frequency response; a dynamic brake is optional. It tolerates voltage fluctuations of 170-242/253VAC (50/60Hz) and 5% frequency fluctuations.
Is Your Device Showing These Signs?
The Mitsubishi MRH22KBN commonly experiences issues related to IPM (Intelligent Power Module) failures, resulting in compressor malfunction and system shutdown. Troubleshooting often reveals IGBT (Insulated Gate Bipolar Transistor) damage within the IPM, necessitating its replacement. Furthermore, communication errors on the CN10 connector, specifically related to the thermistor circuit, are frequent. Addressing these issues involves verifying thermistor resistance values and inspecting the wiring harness for continuity and shorts, ensuring proper signal transmission to the control board.

Our Repair Process for the
MRH22KBN
Our repair process for the Mitsubishi MRH22KBN begins with a comprehensive system diagnostic to confirm IPM failure, a common issue leading to compressor malfunction and shutdown. Upon confirmation, the IPM is replaced, addressing the inherent IGBT damage. Subsequently, a thorough inspection of the CN10 connector is conducted to identify any communication errors, particularly those affecting the thermistor circuit. Thermistor resistance values are verified against specified parameters, and the wiring harness is meticulously inspected for continuity and shorts. Any identified wiring issues are corrected to ensure proper signal transmission to the control board, completing the repair.
