DC brake current
P4.2.2 ab
Minimum value: DriveNomCurrCT*15/100
A
Description: Defines the current level injected into the motor during DC-braking.
Start DC brake time
P4.2.3 ab
0.00 s
Minimum value:
Description: This parameter defines the time the drive injects DC braking current before starting to ramp. This can be used to stop motors that are
potentially spinning before a run command is
spinning before a run command is given.
Stop DC brake frequency
P4.2.4 ab
0.10 Hz
Minimum value:
Description: During a ramp to stop, this parameter defines the output frequency to be below to begin DC braking.
Stop DC brake time
P4.2.5 ab
Minimum value: 0.00 s
Determines the length of DC braking while stopping.
Description:
0.00 = DC brake is not used; or
>0.0 = The amount of time DC-braking will occur after falling below the stop DC brake frequency.
