Description:
DC Braking duration at the stop. Figure 11.9 on page 11-11 shows the braking behavior at the stop, where the
dead time for the de-magnetization of the motor can be observed. This time is proportional to the speed at the
moment of the injection of direct current.

Figure 11.9: Actuation of DC Braking
During the braking process, if the inverter is enabled, the braking is interrupted and the inverter will start
operating normally.
ATTENTION!
The DC Braking can continue acting even if the motor has already stopped. Be careful with the
thermal dimensioning of the motor for short-period cyclic braking.
P0301 – Frequency to Begin DC Braking at Stop
Adjustable
Range:
0.0 to 500.0 Hz Factory
Setting:
3.0 Hz

Description:
This parameter establishes the initial point to apply the DC Braking at the stop when the inverter is disabled by
ramp, as per
Figure 11.9 on page 11-11 .
