  • Overheating: The VFD's internal temperature exceeds safe operating limits.

  • Blown Fuses: Internal fuses blow due to overcurrent or other faults.

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

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

  • Parameter Corruption: Loss or corruption of VFD configuration parameters.

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

  • Motor Stalling: The motor connected to the VFD stalls or fails to start correctly.

  • Current Imbalance: Uneven current distribution among the motor phases.
