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.
