[Dig In Status]
1 “Acc 2 & 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 1-19
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” (Default) Refer to A070
- A073 [Preset Freq x].
Important: Digital Inputs have priority for frequency control
when programmed as a Preset Speed and are active. Refer
to the flowchart on 1-18
for more information on speed
reference control priority.
5 “Local” When active, sets integral keypad as start source and
potentiometer on the integral keypad as speed source.
6 “Comm Port”  When active, sets communications device as default start/
speed command source.
 Can only be tied to one input.
7 “Clear Fault” When active, clears an active fault.
8 “RampStop,CF” Causes drive to immediately ramp to a stop regardless of how
P037
[Stop Mode] is set.
9 “CoastStop,CF” Causes drive to immediately coast to a stop regardless of
how P037
[Stop Mode] is set.
10 “DCInjStop,CF” Causes drive to immediately begin a DC Injection stop
regardless of how P037
[Stop Mode] is set.
11 “Jog Forward” 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.
Stop drive before changing this parameter.
