8.4.5 Parameter group 4 (Brake chopper and DC brake)
Table 44: Parameter group 4 (Motor braking)
Parameter 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.

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.
Note:
With internal brake resistor, do not change the value.

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 thermal protection of the brake resistor.
Note:
With internal brake resistor, do not change the value.

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.
