KPS Intermediate Circuit Overvoltage During Operation

Hva betyr Overvoltage PMx ?

An overvoltage condition has been detected in the intermediate circuit of the KPS module (PMx) during operation. This can be caused by excessively high mains voltage or a defective ballast switch not dissipating regenerative energy.

• Intermediate circuit voltage exceeds the safe limit during operation.
• Regenerative braking feedback too high without sufficient load.
• Power supply fluctuations.
• Faulty capacitor bank in the intermediate circuit.
• Overvoltage protection device failure.

1. 1

   Measure the incoming mains voltage at the KPS input terminals. If it exceeds specifications, identify and rectify the source of the high voltage.

2. 2

   If the mains voltage is within specifications, the ballast switch inside the KPS module may be defective; exchange the KPS module.
