Product Description
The Mitsubishi MDS-B-CVE-370, a 37 kW power supply and servo converter for CNC applications within the MDS Servo Drives series, accepts 200-230 VAC 3-phase input and supports 0.2-121 Amps across 50/60 Hz. Featuring forced air cooling and digital/analog control, this 10.84 kg unit is now superseded by the MDS-C1-CV-370.
Is Your Device Showing These Signs?
The Mitsubishi MDS-B-CVE-370 servo drive commonly experiences issues related to power module failures, resulting in alarms indicative of overcurrent or overvoltage conditions. Troubleshooting often reveals degraded electrolytic capacitors on the DC bus, necessitating replacement to restore stable voltage levels and prevent erratic servo motor behavior. Encoder feedback problems also occur, leading to positioning errors and potential axis drift; inspect encoder cables and the encoder itself for damage or signal degradation. Furthermore, communication errors with the CNC controller arise, requiring verification of the fiber optic connections and parameter settings to ensure proper data transmission and operational integrity.

Our Repair Process for the
MDS-B-CVE-370
Our repair process for the Mitsubishi MDS-B-CVE-370 servo drive begins with a comprehensive evaluation to pinpoint the root cause of the failure. Power module failures, frequently indicated by overcurrent or overvoltage alarms, are addressed by replacing degraded electrolytic capacitors on the DC bus to stabilize voltage levels and eliminate erratic servo motor behavior. Encoder feedback problems, which manifest as positioning errors or axis drift, necessitate a thorough inspection of encoder cables and the encoder itself; damaged components are replaced. Communication errors with the CNC controller are resolved by verifying fiber optic connections and parameter settings, ensuring seamless data transmission and restored operational integrity.
