5-58 Revision August 2006, SE08, SW V2.61
Group 8: Special Parameters
8-00 DC Braking Current Level Unit: 1
Settings d0 to d30% Factory Setting: d0
This parameter determines the level of DC Braking Voltage Level output to the motor during
start-up and stopping. When setting DC Braking Voltage, the Maximum Output Voltage (Pr.1-
02) is regarded as 100%. It is recommended to start with a low DC Braking Voltage Level and
then increase until proper holding torque has been attained.
8-01 DC Braking Time during Start-up Unit: 0.1
Settings d0.0 to d60.0 sec Factory Setting: d0.0
This parameter determines the duration of time that the DC Braking Current will be applied to
the motor during the AC drive start-up.
8-02 DC Braking Time during Stopping Unit: 0.1
Settings d0.0 to d60.0 sec Factory Setting: d0.0
This parameter determines the duration of time that the DC braking voltage will be applied to
the motor during stopping. If stopping with DC Braking is desired, then Pr.2-02 must be set to
RAMP stop (d0).
8-03 Start-Point for DC Braking Unit: 0.1
Settings d0.0 to d400Hz Factory Setting: d0.0
This parameter determines the frequency when DC Braking will begin during deceleration.
