Settings of the internal brake chopper.
Displays the estimated temperature of the braking resistor.
The value is given in percent of the temperature the resistor
reaches when loaded with the power defined by parameter
43.09 Brake resistor Pmax
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
• overvoltage control is switched off (parameter
Overvoltage control)
• the supply voltage range (parameter
has been selected correctly.
Brake chopper control disabled.
