start-up and stopping. When setting DC Braking Current, the Rated Current (Pr.00-01)
is regarded as 100%. It is recommended to start with a low DC Braking Current Level
and then increase until proper holding torque has been attained.
08 - 01
DC Braking Time during Start-up Factory Setting: 0.0
Settings 0.0 to 60.0 sec Unit: 0.1sec
 This parameter determines the duration that the DC Braking current will be applied to
the motor during the AC drive start-up. When the time is up, the AC drive will start
acceleration from the Minimum Frequency (Pr.01-05).
08 - 02
DC Braking Time during Stopping
Factory Setting: d 0.0
Settings 0.0 to 60.0 sec Unit: 0.1sec
 This parameter determines the duration that the DC Braking current will be applied to
the motor during stopping. If stopping with DC Braking is desired, the Pr.02-02 must be
set to RAMP stop.
08 - 03
Start-Point for DC Braking Factory Setting: 0.00
Settings 0.00 to 400.00Hz Unit: 0.01Hz

starts, such as fans and pumps. Under such circumstances, DC Braking can be
executed to hold the load in position before applying a forward motion.
