Braking circuit commissioning

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 drive
• Adjust any other relevant parameters in group 48.
WARNING! If the drive 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.
