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 error threshold for overvoltage due to a too high braking energy or a too high mains voltage. The error threshold (display in 0x2540:006 (P208.06) results from the setting of the rated mains voltage in 0x2540:001 (P208.01).
