Troubleshooting VFD Problems Overvoltage Fault Voltage

Solution This issue of drive overvoltage fault due to utility capacitor switching can be prevented by adding a line reactor or a DC choke to the drive.Note that this will only work to prevent overvoltage fault on drives that are in operation (running condition). When the drive is in an idle ON state, adding a line reactor or DC choke may not solve the problem with capacitor switching and the
