Pr.29 DC Braking Time During Start-up
Factory Setting 0.0 Sec
Units 0.1 Sec
Parameter value 0.0 - 5.0 Sec
This parameter determines the time duration that DC braking current will be applied to
the motor during the AC drive start-up.
Pr.30 DC Braking Time During Stopping
Factory Setting 0.0 Sec
Units 0.1 Sec
Parameter value 0.0 - 25.0 Sec
This parameter determines the time duration that DC braking current will be applied to
the motor when the Motor Stop Method (Pr.02) is set to "Ramp Stop".
Pr.31 DC Braking Start-up Frequency
Factory Setting 0.00 Hz
Units 0.01 Hz
Parameter value 0.00 - 60.00 Hz
This parameter determines the Start-up Frequency for DC braking when the AC drive
starts to decelerate. The frequency may be set in 0.1 Hz increments. When the value is
less than that specified by Pr.08, Minimum Output Frequency, the start-up frequency
for DC braking will be the value specified by this parameter.
