PowerFlex 700 Adjustable Frequency AC Drive – Frames 7…10
Common Symptoms and Corrective Actions
Drive does not Start from Start or Run Inputs wired to the terminal block.
Drive does not Start from Human Interface Module (HIM).
Drive does not respond to changes in speed command.
Cause(s) Indication Corrective Action
Drive is Faulted Flashing red status light • Clear fault.
• Press Stop
• Cycle power
• Set [Fault Clear] to 1
• “Clear Faults” on the HIM Diagnostic
menu.
Incorrect input wiring. Refer to the

Forward, Run Reverse or Jog input.
• 3 wire control requires Start and
Stop inputs.
• Jumper from terminal 25 to 26 is
required.
None Wire inputs correctly and/or install jumper.
Incorrect digital input programming.
• Mutually exclusive choices have
been made (i.e., Jog and Jog
Forward).
• 2 wire and 3 wire programming
can be conflicting.
• Exclusive functions (i.e, direction
control) can have multiple inputs
configured.
• Stop is factory default and is not
wired.
None Program [Digital Inx Sel], parameters
361…366 for correct inputs.
Start or Run programming can be missing.
Flashing yellow status light
and “DigIn CflctB” indication
on LCD HIM.
[Drive Status 2] shows type 2
alarm(s). Program [Digital Inx Sel] to resolve conflicts.
Remove multiple selections for the same
function.
Install stop button to apply a signal at stop

control. HIM Start button is disabled
for 2 wire control unless param. 192,
bit 1 = “1.” None If 2 wire control is required, no action
needed.
If 3 wire control is required, program [Digital
Inx Sel] for correct inputs.
Cause(s) Indication Corrective Action
No value is coming from the source of
the command. LCD HIM Status Line indicates
“At Speed” and output is 0
Hz. 1. If the source is an analog input, check
wiring and use a meter to check for
presence of signal.
2. Check [Commanded Speed], parameter
002 for correct source.
Incorrect reference source has been
programmed. None 3. Check parameter 213, [Speed Ref Source]
for the source of the speed reference.
4. Reprogram parameter 090, [Speed Ref A
Sel] for correct source.
Incorrect Reference source is being
selected via remote device or digital
inputs. None 5. Check parameter 209, [Drive Status 1],
bits 12 & 13 for unexpected source
selections.
6. Check parameter 216 [Dig In Status] to
see if inputs are selecting an alternate
source.
7. Reprogram digital inputs to correct
“Speed Sel x” option.
