CH 5-9 Group 8: Special Parameters

8 - 00 DC Braking Voltage Level Factory Setting: d 0

Settings d 0 ⇔ d30% Unit: 1%

& 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 Factory Setting: d

0.0

Settings d 0.0 to d 60.0Sec Unit: 0.1Sec

& This parameter determines the duration of time that the DC Braking Current

will be applied to the motor during the AC drive start-up. DC Braking will be

applied for the time set in this parameter until the Minimum Frequency is

reached during acceleration.

8 - 02 DC Braking Time during Stopping Factory Setting: d

0.0

Settings d 0.0 to d 60.0Sec Unit: 0.1Sec

& 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 (d 0).

8 - 03 Start-Point for DC Braking Factory Setting: d 0.0

Settings d 0.0 to d 400Hz Unit: 0.1Hz

& This parameter determines the frequency when DC Braking will begin during

deceleration.
