48.05 R BR FW block: BRAKE CHOPPER (see above)
Defines the resistance value of the braking resistor. The value is used for braking chopper protection.
0.1…1000 ohm Resistance.
48.06 BR TEMP FAULTLIM FW block: BRAKE CHOPPER (see above)
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 48.04 BR
POWER MAX CNT.
When the limit is exceeded the drive trips on fault BR OVERHEAT.
0…150% Resistor temperature fault limit.
48.07 BR TEMP ALARMLIM FW block: BRAKE CHOPPER (see above)
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 48.04 BR
POWER MAX CNT.
When limit is exceeded the drive generates alarm BR OVERHEAT.
0…150% Resistor temperature alarm limit.
