Settings for the internal brake chopper.
Displays the estimated temperature of the brake resistor, or
how close the brake resistor is to being too hot.
The value is given in percent where 100% is the temperature

100% time has elapsed.
This parameter is read-only.
Estimated brake resistor temperature.
Enables brake chopper control.
Note: Before enabling brake chopper control, ensure that
• a brake resistor is connected, and
• the supply voltage range (parameter
has been selected correctly.
Brake chopper control disabled.
Brake chopper control enabled with resistor overload
protection.
Note: Before using this setting, ensure that overvoltage

Brake chopper control enabled without resistor overload
protection. This setting can be used, for example, if the
resistor is equipped with a thermal circuit breaker that is wired
to stop the drive if the resistor overheats.
Before using this setting, ensure that overvoltage control is
