Allen-Bradley PowerFlex User Manual

2-160 Stop Modes
5. Ramp To Hold is selected by setting [Stop Select x]. The drive will
ramp the frequency to zero based on the deceleration time programmed
into [Decel Time 1/2]. Once the drive reaches zero hertz, a DC Injection
holding current is applied to the motor. The level of current is set in [DC
Brake Level]. The DC hold is removed only by removing the “Enable”
input or by a valid start input.
Motor speed during and after the application of DC depends upon the
combination of the these two parameter settings, and the mechanical
system. The drive output voltage will be zero when the hold time is
finished.
