Common Unidrive Power Module Problems We Repair

Unidrive power modules can experience a variety of issues that can disrupt your operations. Our technicians are highly skilled in diagnosing and repairing these problems, ensuring your equipment returns to optimal performance.

  • Brake Resistor Faults: Issues with the braking resistor circuit, often indicated by error codes related to excessive braking energy or resistor failure. This is a common issue we address with expertise.

  • Overcurrent Faults: Excessive current draw within the power module, potentially caused by motor issues, short circuits, or component failure.

  • Overvoltage Faults: Voltage spikes or surges that exceed the module's operating limits, leading to component damage.

  • Undervoltage Faults: Insufficient voltage supply to the power module, preventing proper operation.

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

  • Capacitor Failures: Degradation or failure of capacitors within the power module, leading to instability and performance issues.

  • Communication Errors: Loss of communication between the power module and the drive controller, preventing proper control and monitoring.

  • Overheating: Excessive heat buildup within the power module, potentially caused by inadequate cooling, component failure, or overload conditions.

  • Blown Fuses: Fuses blowing due to overcurrent or short circuit conditions within the power module.

  • Gate Drive Circuit Failures: Malfunctions in the gate drive circuitry that controls the IGBTs, leading to improper switching and performance issues.

  • Power Supply Issues: Problems with the internal power supply that provides power to the control circuitry within the power module.

  • Dead Module: The module is completely unresponsive and shows no signs of power.
