48 BRAKE CHOPPER
Firmware block:
BRAKE CHOPPER
(48)
This block configures the brake
chopper control and supervision.
48.01
BC ENABLE
(see above)
Enables the brake chopper control.
Note:
Before enabling brake chopper control, ensure the brake resistor is installed and the
overvoltage control is switched off (parameter
). The drive has a built-in
brake chopper.
(0)
DISABLE
Brake chopper control disabled.
(1)
ENABLETHERM
Enable brake chopper control with resistor overload protection.
(2)
ENABLE
Enable brake chopper control without resistor overload protection.
This setting can be used, for example, if the resistor is equipped with a
thermal circuit breaker that is wired to stop the drive if the resistor
overheats.
48.02
BC RUN-TIME ENA
(see above)
Selects the source for quick run-time brake chopper control.
0 = Brake chopper IGBT pulses are cut off.
1 = Normal brake chopper IGBT modulation. The overvoltage control is automatically switched off.
This parameter can be used to program the chopper control to function only when the drive is
operating in generating mode.
Bit pointer: Group, index and bit
48.03
BRTHERMTIMECONST
(see above)
Defines the thermal time constant of the brake resistor for overload protection.
0…10000 s
Brake resistor thermal time constant.
48.04
BR POWER MAX CNT
(see above)
Defines the maximum continuous braking power which will raise the resistor temperature to the
maximum allowed value. The value is used in the overload protection.
0…10000 kW
Maximum continuous braking power.
