10. Troubleshooting

This section provides solutions for common issues. For complex problems, contact technical support.

Common Issues and Solutions:

• VFD does not power on:
  Possible Cause: No input power or incorrect wiring.
  Solution: Check power supply connections, circuit breakers, and ensure input voltage matches specifications.
• Motor does not run:
  Possible Cause: Incorrect wiring, motor parameters not set, or fault condition.
  Solution: Verify motor wiring (U, V, W terminals), check motor parameters in the VFD settings, and clear any active fault codes using the STOP/RESET key.
• Motor speed is unstable:
  Possible Cause: Incorrect acceleration/deceleration times, or load fluctuations.
  Solution: Adjust acceleration/deceleration parameters. Ensure the VFD is appropriately sized for the motor and load.
• Overcurrent/Overload Fault:
  Possible Cause: Motor overload, short circuit in motor wiring, or rapid acceleration.
  Solution: Reduce motor load, check motor wiring for shorts, increase acceleration time parameter.
• Overvoltage/Undervoltage Fault:
  Possible Cause: Unstable input power, regenerative braking, or incorrect voltage settings.
  Solution: Check input power stability. If using with high inertia loads, consider adding a braking resistor (if supported by model). Verify voltage parameters.
