DC braking level setting
Factory setting
d 0.0
Setting range
d0.0<->d 60.0S
Unit

This parameter is to set time lasting of DC braking voltage input to motor during start of AC motor
drive.

DC braking time setting at stopping
Factory setting
d 0.0
Setting range
d0.0<->d 60.0S
Unit
0.1S
This parameter is to set time lasting of DC braking voltage input to motor during braking. If DC
braking is necessary at stop, this function shall be available if Parameter 2-04 is set to deceleration
and stop (d0).
8-03
Starting frequency of DC braking at stopping
Factory setting
d 1.0
Setting range
d 0.1<->d 60.0Hz
Unit
0.1Hz
This parameter is to set DC braking starting frequency from deceleration to stop of AC motor drive.
When set value is below min frequency (1-05), starting frequency of DC braking shall begin from
min frequency.

Techniques Forum: DC braking before running is generally applied in circumstances which load can
move when machine such as fan or pumps stop. For these loads, prior to AC motor drive start, motor is
generally in free rotating, while direction is uncertain. Prior to start, it is advisable to perform DC braking
before starting motor. DC braking at stopping is generally used in circumstances when motor is
suggested to be braked quickly, or for control of location, such as traveling crane and cutting machine.

Restarting after momentary power loss
Factory setting
d 2.0
Setting range
d 0.3<->d 5.0S
Unit
0.1S
This parameter shall set Max allowable time for power loss in case of momentary power loss and if
function of Restarting after momentary power loss is started. If power supply breaking time
exceeds Max allowable time, output of AC motor drive shall stop after power resupplied.
