Allen-Bradley PowerFlex 70 Reference Manual

Stop Modes 2-203
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].
In this mode, the braking is applied Continuously. [DC Hold Time] has
no effect in this mode. Braking will continue until one of the following
events occur:
– The Enable Input is opened, or . . .
– A Start command is re-issued.
Again, caution must be exercised to not overheat the motor by applying
excess voltage and/or for excess time, particularly if the motor is not
rotating.
