Remedy
- Reduce dynamic performance of the load profile.
- Check mains voltage.
- Check settings for brake energy management.
- 0x2541:001 (P706.01) = [0]: Connect brake resistor to the power unit and activate the integrated brake chopper.
Cause
DC-bus voltage has exceeded the warning threshold for overvoltage set in 0x2540:005 (P208.05) due to a too high braking energy or a too high mains voltage.
