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.

1 = 1 % / 1 = 1 %Brake resistor temperature fault limit.0...150 %
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
