DC Braking Current (DC Injection Current)
Parameter #
28
Parameter Name
DC braking current
Factory Setting
d0000%
Units
1%
Parameter value
d0000 - d0100%
This parameter determines the DC current that will be applied to the motor during
braking when the Motor Stop Method is set to “RAMP stop” (refer to Pr.02). DC
braking current is set in increments of 1%. A setting of 100% is equal to the rated
current of drive.
Note: When setting this parameter, begin at a lower current level then increase the
value until sufficient holding torque is achieved. The rated motor current cannot be
exceeded.
Parameter #
29
Parameter Name
DC braking time during start-up
Factory Setting
d000.0 Sec
Units
0.1 Sec
Parameter value
d000.0 - d005.0 Sec
This parameter determines the time duration that DC braking current will be applied
to the motor during the AC drive start-up.
Parameter #
30
Parameter Name
DC braking time during stopping
Factory Setting
d000.0 Sec
Units
0.1 Sec
Parameter value
d000.0 - d025.0 Sec
This parameter determines the time duration that DC braking current will be applied
to the motor when the Motor Stop Method is set to
“
Ramp Stop
”
.
Parameter #
31
Parameter Name
DC braking starting frequency
Factory Setting
d000.0 Hz
Units
0.1 Hz
Parameter value
d000.0 - d060.0 Hz
This parameter determines the frequency at which DC breaking will start during AC
drive deceleration. The frequency may be set in 0.1 Hz increments.
When the preset value is less than that specified by Pr.08 (Minimum output
frequency), the starting frequency for DC braking will be the Pr.08 frequency.
