4-6 Troubleshooting
Drive does not Start from Integral Keypad.
Drive does not respond to changes in speed command.
Motor and/or drive will not accelerate to commanded speed.
Cause(s) Indication Corrective Action
Integral keypad is not enabled. Green LED above Start key is
not illuminated.
• Set parameter P036 [Star
t
Source] to option 0 “Keypad”.
• Set parameter A051 - A052
[Digital Inx Sel] to option 5
“Local” and activate the input.
I/O Terminal 01 “Stop” input is
not present.
None Wire inputs correctly and/or install
jumper.
Cause(s) Indication Corrective Action
No value is coming from the
source of the command.
The drive “Run” indicator is lit
and output is 0 Hz.
• Check d012 [Control Source] for
correct source.
• If the source is an analog input,
check wiring and use a meter to
check for presence of signal.
• Check d002 [Commanded F
req]
to verify correct command.
Incorrect reference source is
being selected via remote
device or digital inputs.
None • Check d012 [Control Source] for
correct source.
• Check d014 [Dig In Status] to
see if inputs are selecting an
alternate source. Verify settings
for A051 - A052 [Digital Inx Sel].
• Check P038 [Speed Reference]
for the source of the speed
reference. Reprogram as
necessary.
• Review the Speed Reference
Control chart on page
1-17.
Cause(s) Indication Corrective Action
Acceleration time is excessive. None Reprogram P039 [Accel Time 1] or
A067 [Accel Time 2].
Excess load or short
acceleration times force the
drive into current limit, slowing
or stopping acceleration.
None Compare d003 [Output Current]
with
A089 [Current Limit]
.
Remove excess load or reprogram
P039 [Accel
Time 1] or A067 [Accel
Time 2].
Check for improper A084 [Star
t
Boost] setting.
Speed command source or
value is not as expected.
None Verify d002 [Commanded Freq].
Check d012 [Control Source]
for the
proper Speed Command.
Programming is preventing the
drive output from exceeding
limiting values.
None Check P035 [Maxim
um Freq] to
insure that speed is not limited by
programming.
