How to fix DC bus overvoltage on Lenze i550 Inverter?
To address DC bus overvoltage, consider the following: * Reduce dynamic performance of the load profile. * Check the mains voltage. * Review the settings for braking energy management. * Connect a brake resistor to the power unit and activate the integrated brake chopper by setting P706.01 = 0 (brake resistance).
