0.0 to 15.0s The DC braking feature provides a motor fast stop via
[ 0.0 ] DC current injection.
0.1s The applied DC braking current, that is proportional to
the braking torque, is set at P302.
0.0 to 15.0Hz The figures below show the DC branking operation at
[ 1.0Hz ] the two possible conditions: ramp disabling and general
0.1Hz disabling.
0.0 to 100%
[ 50.0% ]
0.1%
Before DC braking starts, there is a "Dead Time" (motor
runs freely) required for the motor demagnetization. This
time is function of the motor speed at which the DC
braking occurs (output frequency)
During the DC braking the LED display flashes
If the inverter is enabled during the braking process, this
process will be aborted and motor operates normally.
