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
