Overvoltage Condition (Load Side Power-up, Adv. Code 2)
Vacon · X4 AC Drive
What does 13 mean?
This fault signifies an overvoltage condition detected on the load (motor) side during power-up. While related to input overvoltage, this advanced code might point to an issue specific to the motor connection or residual voltage on the motor leads. High voltage can damage the motor insulation or the drive's output stage.
Complete Troubleshooting Guide
- 1
Verify that the incoming line power at the drive's input terminals is stable and within specification before and during power-up.
- 2
Ensure the motor is properly connected to the drive and that there are no external sources (e.g., back-EMF from a spinning motor, shared bus) feeding voltage into the motor leads during power-up.
- 3
If consistently high voltage is observed, consider adding an input line reactor or isolation transformer.
- 4
Check the motor cabling for any capacitive coupling issues, especially with long motor lead lengths, that could cause voltage spikes on power-up.
