2-48 Digital Inputs
Table 2.K Digital Input Function List
Input Function Detailed Descriptions
• Stop - Clear Faults
An open input will cause the drive to stop and become “not ready”. A
closed input will allow the drive to run.
If “Start” is configured, then “Stop - Clear Faults” must also be
configured. Otherwise, a digital input configuration alarm will occur.
“Stop - Clear Faults” is optional in all other circumstances.
An open to closed transition is interpreted as a Clear Faults request. The
drive will clear any existing faults. The terminal block bit must be set in
the [Fault Mask] and [Logic Mask] parameters in order for the terminal
block to clear faults using this input function.
Input Function Name Purpose

Clear Faults (open to closed transition)
Run Forward Run in forward direction (2-wire start mode)
Run Reverse Run in reverse direction (2-wire start mode)
Run Run in current direction (2-wire start mode)
Start Start drive (3-wire start mode)
Forward/Reverse Set drive direction (3-wire mode only)
Jog Jog drive
Jog Forward Jog in forward direction
Jog Reverse Jog in reverse direction
Speed Select 3
Speed Select 2
Speed Select 1
Select which Speed reference the drive uses.
Auto/Manual Allows terminal block to assume complete control of Speed
Reference.
Accel 2 Select acceleration rate 1 or 2.
Decel 2 Select deceleration rate 1 or 2.
Accel 2 & Decel 2 Select acceleration rate 1 and deceleration rate 1 or
acceleration rate 2 and deceleration rate 2.
MOP Increment Increment MOP (Motor Operated Pot Function Speed ref)
MOP Decrement Decrement MOP (Motor Operated Pot Function Speed ref)
Stop Mode B Select Stop Mode A (open) or B (closed)
Bus Regulation Mode B Select which bus regulation mode to use
PI Enable Enable Process PI loop.
PI Hold Hold integrator for Process PI loop at current value.
PI Reset Clamp integrator for Process PI loop to 0.
Auxiliary Fault Open to cause “auxiliary fault” (external string).
Local Control Allows terminal block to assume complete control of drive
logic.
Clear Faults Clear faults and return drive to ready status.
Enable Open input causes drive to coast to stop, disallows start.
Exclusive Link Exclusive Link – digital input is routed through to digital
output, no other use.
Power Loss Level (PowerFlex 700 only) Selects between using fixed value for power loss level and
getting the level from a parameter
Precharge Enable (PowerFlex 700 only) If common bus configuration, denotes whether drive is
disconnected from DC bus or not. Controls precharge
sequence on reconnection to bus.
