Description
Defines the resistance value of the brake resistor. The
value is used for the brake chopper protection based
on the thermal model. See parameter
chopper function.
Brake resistor resistance value.
Selects the fault limit for the brake resistor protection
based on the thermal model. See parameter
chopper function. When the limit is exceeded, the drive
trips on fault 7183 BR excess
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
Brake resistor temperature fault limit.
Selects 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
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
