0.0 Ohm / real32Defines the resistance value of the brake resistor. The
value is used for the brake chopper protection based
on the thermal model. See parameter 43.6 Brake
chopper function.

1 = 1 Ohm / 1 = 1 OhmBrake resistor resistance value.0.0 ... 1000.0 Ohm
105 % / real32Selects the fault limit for the brake resistor protection
based on the thermal model. See parameter 43.6 Brake
chopper function. When the limit is exceeded, the drive
trips on fault 7183 BR excess temperature.
The value is given in percent of the temperature the
resistor reaches when loaded with the power defined
by parameter 43.9 Brake resistor max cont power.

95 % / real32Selects the warning limit for the brake resistor
protection based on the thermal model. See parameter
43.6 Brake chopper function. When the limit is
exceeded, the drive generates a A793 BR excess
temperature warning.
The value is given in percent of the temperature the
resistor reaches when loaded with the power defined
by parameter 43.9 Brake resistor max cont power.
