Common Mitsubishi Inverter Problems We Repair

Mitsubishi inverters, while reliable, can experience failures due to various factors such as age, environmental conditions, and operational stress. Roc Industrial LLC is equipped to address a wide range of common and complex issues. Here are some common problems we repair:

  • No Output Voltage: The inverter fails to provide the necessary output voltage to the motor.

  • Overcurrent Faults: The inverter trips due to excessive current draw, often caused by motor issues or short circuits.

  • Overvoltage Faults: The inverter experiences voltage spikes that trigger fault protection.

  • Undervoltage Faults: The input voltage drops below the acceptable level, causing the inverter to shut down.

  • Communication Errors: The inverter loses communication with the control system or other devices.

  • Overheating: The inverter's internal temperature exceeds the safe operating limit, leading to shutdown.

  • Blown Fuses: Internal fuses blow due to power surges or component failures.

  • Encoder Faults: Issues with the encoder feedback signal, affecting motor control accuracy.

  • Drive Not Responding: The inverter does not respond to commands or inputs.

  • IGBT Failures: Failure of the Insulated Gate Bipolar Transistors (IGBTs), critical for power switching.

  • Capacitor Failures: Degradation or failure of capacitors, leading to voltage instability.

  • Display Issues: Problems with the inverter's display screen, making it difficult to monitor parameters.

  • Parameter Corruption: Loss or corruption of inverter parameters, affecting performance.
