328 Parameters
Selects the fault limit for the brake resistor protection based
on the thermal model. See parameter
.
When the limit is exceeded, the drive trips on fault
The value is given in percent of the temperature the resistor
reaches when loaded with the power defined by parameter
105%
0 … 150%
Brake resistor temperature fault limit.
1 = 1%
Selects the warning limit for the brake resistor protection
based on the thermal model. See parameter
When the limit is exceeded, the drive
generates a
warning.
The value is given in percent of the temperature the resistor
reaches when loaded with the power defined by parameter
95%
0 … 150%
