Selects the function for the digital inputs. I/O Terminal 03 is fully programmable via E202 [Digital Term
3]. Refer to the flowchart on page 1-27
for more information on speed reference control priority.
Options 0 “Not Used” Terminal has no function but can be read over network
communications via b014
[Dig In Status].
1 “Acc/Dec Sel1” If active, can determine which Accel/Decel time will be used
for all ramp rates except jog. Can be applied to one input
only. Refer to A067
[Accel Time 2] for details. Can be used
with option 28 “Acc/Dec Sel2” for additional Accel/Decel
times.
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)
In Velocity mode (P038
≠ 9) selects a preset frequency.
Refer to A070
- A077 [Preset Freq x].
In Positioning mode (P038 = 9) selects a preset frequency
and position. Refer to E230
- E244 [Step Units x].
Important: Digital Inputs have priority for frequency and
position control when programmed as Preset Speed and are
active. Refer to the flowchart on page 1-27
for more
information on speed reference control priority.
5 “Reserved”
6 “Comm Port” • When active, sets communications device as default start/
speed command source.
• Can only be tied to one input.
7 “Clear Fault”
(A053 Default)
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”
(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.
Stop drive before changing this parameter.
