Unit Description / Notes
The option 1.25 kHz is not valid for the Vector Control (P202 = 3 or 4).
The option 10 kHz is not valid for the Sensorless Vector Control (P202 = 3)
and for the models with supply voltage between 500 V and 690 V (2.9 A to
79 A/500-600 V, 107 A to 472 A/500-690 V and 100 A to 428 A/660-690 V).
0.0 to 15.0
The DC braking feature provides a motor fast stop through the injection of
[ 0.0 ] DC current.
0.1 s
This parameter sets the DC Braking Time when the inverter is operating
in the V/F, VVW or Sensorless Vector Control modes.
Figure 6.40 shows the operation of the DC Braking with a ramp to stop
(stop command). Refer to P301:
a) V/F Control
b) VVW and Sensorless Control
