1 “Acc & Dec 2” • When active, A067
[Accel Time 2] and A068 [Decel Time
2] are used for all ramp rates except Jog.
• Can only be tied to one input.
Refer to the flowchart on page 1-24
for more information on
Accel/Decel selection.
2 “Jog” • When input is present, drive accelerates according to the
value set in A079
[Jog Accel/Decel] and ramps to the
value set in A078
[Jog Frequency].
• When input is removed, drive ramps to a stop according to
the value set in A079
[Jog Accel/Decel].
• A valid “Start” command will override this input.
3 “Aux Fault” When enabled, an F2 Auxiliary Input
fault will occur when the
input is removed.
4 “Preset Freq”
(A051 & A052 Default)
Refer to A070
- A077 [Preset Freq x].

when programmed as Preset Speed and are active. Refer to
the flowchart on page 1-23
for more information on speed
reference control priority.
5 “Local”
(A053 Default)
When active, sets integral keypad as start source and
potentiometer on the integral keypad as speed source.

11 “Jog Forward”
(A054 Default)
Drive accelerates to A078
[Jog Frequency] according to A079
[Jog Accel/Decel] and ramps to stop when input becomes
inactive. A valid start will override this command.
12 “Jog Reverse” Drive accelerates to A078
[Jog Frequency] according to A079
[Jog Accel/Decel] and ramps to stop when input becomes
inactive. A valid start will override this command.
