About Mitsubishi Inverters

Mitsubishi Electric is a global leader in automation and control technologies, renowned for its high-quality and innovative products. Their inverters, also known as variable frequency drives (VFDs), are essential components in a wide range of industrial applications. Mitsubishi inverters are designed to precisely control the speed and torque of electric motors, optimizing energy efficiency and improving process control. These inverters are known for their robust design, advanced features, and reliable performance in demanding environments.


Mitsubishi inverters are widely used in industries such as manufacturing, robotics, HVAC, water treatment, and energy production. They are integral to controlling motors in pumps, fans, conveyors, and other critical equipment. The FR series, in particular, is a popular choice for its versatility and ease of use. When these inverters fail, it can lead to significant downtime and production losses. Roc Industrial LLC specializes in providing comprehensive repair services for all Mitsubishi inverter models, ensuring minimal disruption to your operations.

Common Mitsubishi Inverter Problems We Repair

Mitsubishi inverters are built to withstand harsh industrial environments, but they are still susceptible to failures due to age, wear and tear, power surges, and environmental factors. Recognizing these common issues is the first step in getting your equipment back online. Here are some of the most common problems we encounter when repairing Mitsubishi inverters:

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

  • Overvoltage/Undervoltage Errors: The inverter detects voltage levels outside the acceptable range.

  • Overcurrent Errors: The inverter detects excessive current draw, often indicating a motor or wiring issue.

  • Communication Errors: The inverter fails to communicate with the control system or other devices.

  • Overheating: The inverter's internal temperature exceeds safe limits, potentially damaging components.

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

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

  • Drive Trips: The inverter shuts down unexpectedly due to a detected fault.

  • Parameter Errors: Incorrect or corrupted parameter settings causing malfunction.

  • IGBT Failures: Failure of the Insulated Gate Bipolar Transistors (IGBTs), which are critical switching components.

  • 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 status and parameters.
