48.05 R BR
Defines the resistance value of the braking resistor. The value is used for braking chopper protection.
0.1...1000 ohm
48.06 BR TEMP FAULTLIM
Selects the fault limit for the braking resistor temperature supervision. The value is given in percent of
the temperature the resistor reaches when loaded with the power defined by parameter
POWER MAX
When the limit is exceeded the drive trips on fault BR OVERHEAT.
0...150%
48.07 BR TEMP ALARMLIM
Selects the alarm limit for the braking resistor temperature supervision. The value is given in percent
of the temperature the resistor reaches when loaded with the power defined by parameter
POWER MAX
When limit is exceeded the drive generates alarm BR OVERHEAT.
0...150%
