E2815

Overvoltage in mains

Bosch Rexroth · IndraDrive C Drive Controllers

What does E2815 mean?

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.

Common Causes

  • 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.

Repair Steps & Checklist

Click steps to track your progress.

  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.
