Rockwell Automation Liqui-Flo AC GP Vector Drive Version 6.4 - Manual (Page 108)

4-26 LiquiFlo AC Drive, Software Reference Version 6.4
The acceleration and deceleration times must be set the same for the S-Curve ramp
to function the same for acceleration as for deceleration. If the deceleration time is set
lower than the acceleration time, the deceleration time specified may not be met.
Jog reference is independent of any other speed reference. Unlike the run speed
reference, the jog speed reference cannot be adjusted using the ▲
or ▼ keys
