Overvoltage in mains

Was bedeutet E2815 ?

The incoming AC mains voltage is above the acceptable operating threshold for the drive's power section. This can lead to excessive DC bus voltage and potential damage to the drive.

• Incoming AC supply voltage surge or overvoltage condition.
• Incorrect mains voltage setting in drive parameters for the actual supply.
• Power line disturbances or instability.
• Lack of proper voltage regulation on the supply side.

1. 1

   Measure the incoming AC mains voltage at the drive's input terminals and verify it is within the drive's specified operating range.

2. 2

   Verify the mains voltage parameter setting in the drive configuration matches the actual incoming supply voltage.

3. 3

   Check for power quality issues on the mains supply using a power analyzer, looking for spikes or prolonged overvoltage conditions.

4. 4

   Ensure that any necessary line reactors or filters are correctly installed and functioning.
