Common Yaskawa VFD Problems We Repair

Yaskawa VFDs are generally reliable, but like any electronic equipment, they can experience failures over time. We understand the frustration and downtime that a malfunctioning VFD can cause. Here are some common problems we repair:

  • No Output: The VFD fails to provide any output voltage to the motor.

  • Overvoltage Fault: The VFD detects an overvoltage condition on the DC bus.

  • Undervoltage Fault: The VFD detects an undervoltage condition on the DC bus.

  • Overcurrent Fault: The VFD detects an overcurrent condition in the output.

  • Communication Errors: The VFD is unable to communicate with the control system.

  • Overheating: The VFD overheats due to excessive load or cooling fan failure.

  • Blown Fuses: Fuses within the VFD blow due to a short circuit or overload.

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

  • Drive trips on acceleration or deceleration: Indicates parameter issues or component failure.

  • Inconsistent Speed Control: Motor speed fluctuates or is not accurately controlled.

  • Display Issues: The VFD display is blank, dim, or shows incorrect information.

  • Parameter Corruption: VFD parameters are lost or corrupted, leading to incorrect operation.

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

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