Common Mitsubishi Drive Module Problems We Repair

Mitsubishi drive modules can experience a variety of issues that can disrupt your operations. Our experienced technicians are skilled at diagnosing and repairing these common failures.

  • No Output: The drive module fails to provide any output voltage or current to the motor.

  • Overvoltage/Overcurrent Faults: The drive module detects excessive voltage or current, triggering a fault condition.

  • Communication Errors: The drive module is unable to communicate with the PLC or other control systems.

  • Overheating: The drive module overheats due to component failure, inadequate cooling, or excessive load.

  • Blown Fuses: Internal fuses blow due to short circuits or component failures.

  • Encoder Faults: Issues with the encoder feedback signal, leading to inaccurate motor control.

  • Drive tripping: The drive shuts down unexpectedly during operation.

  • Power supply failures: Internal power supply components fail, causing the drive to malfunction.
