10.4.5 Parameter group 4 (“Brake chopper and DC brake”)
Table 38: Parameter group 4 (“Motor braking”)
Para-
meter Designation Description Unit Min Max DS
P4-01 DC-Brake Current DC braking is active in all control modes (P6-01 = 0, …, 6)
and with any stop mode (P1-05 = 0, 1, 2).
To enable DC current injection at START set a DC braking
current (P4-01) and a DC braking time at start (P4-02).
After receiving the start signal the Drive injects a DC
current (P4-01) for the time specified at P4-02. After P4-02
times-out, drive resumes normal operation.
To enable DC current injection at STOP set a DC braking
current (P4-01), a DC braking time (P4-04) and a DC braking
frequency (P4-03).
When the drive receives the STOP command, it will start to
decelerate down to 0. As soon as it reaches the frequency
set in P4-03, the drive will start to inject a DC current
(P4-01) for the time specified at P4-04.
After P4-04 times out, PWM is disabled, drive status
changes to STOP. If coast to stop is selected, DC injection
is executed just after receiving the stop command. % 0 100% 0
P4-02 t-DCBrake@Start Duration of DC braking before Start s 0 600 0
P4-03 f-DCBrake@Stop Output frequency in Hz at which DC braking starts during
the deceleration phase. Hz 0 10 1.5
P4-04 t-DCBrake@Stop Duration of DC braking at Stop s 0 600 0
P4-05 Brake Chopper Mode Parameter function only for devices with internal brake
resistor
0: deactivated
1: active in RUN
2: active in RUN and STOP – 0 2 2
P4-06 Brake Resistor Resistance of the brake resistor in Ohms
This value, together with P4-07, is used for the thermal
protection of the brake resistor.
With internal brake resistor, do not change the value. ohms 50 500 400
P4-07 P-Brake Resistor Power of the brake resistor in kW
Resolution 0.1 kW. This value, together with P4-06, is used
for the thermal protection of the brake resistor.
With internal brake resistor, do not change the value. kW 0 20.00 0.1
P4-08 Brake Chopper ED Heat-Up Brake Chopper Duty Cycle
At very low temperatures (< -10 °C) the drive doesn’t work
and indicates “Under temperature” (Fault code 09 “U-t”).
Devices with internal brake resistor can use this to heat up
the device. Parameter P4-08 determines the load cycle. % 0 20.0 2.0
