Cause
The DC bus voltage has exceeded the overvoltage error threshold due to excessive braking energy or an excessively high supply voltage. The error threshold (shown in 0x2540：006) is derived from the rated supply voltage setting in 0x2540：001
Corrective action
• Reduce the dynamic performance of the load profile. • Check the supply voltage tage. • Check the braking energy management settings. • 0x2541：001 = [0]: Connect the braking resistor to the power unit and activate the integrated braking chopper
