For more information, see the appropriate Firmware Manual.
• Enable the braking chopper function. Please note that a braking resistor must be
connected when the chopper is enabled
• Switch off the overvoltage control of the regen supply module
• Adjust any other relevant parameters in group 48.
WARNING! If the regen supply module is equipped with a braking chopper but the
chopper is not enabled by parameter setting, the braking resistor must be
disconnected because the protection against resistor overheating is then not in use.
