IOMM AGZ-5
AGZ 026B through 130B

Symptom Condition
Probable Cause
Solution
The RPM of the motor does
not match the inverter output
frequency setting.
•
Is the maximum frequency setting A_04
correct?
•
Does the monitor function D_01 display
the expected output frequency?
•
Verify the V/f settings match motor
specification.
•
Make sure all scaling (such as A_11 to
A_14) is properly set.
•
Was power turned OFF after a
parameter edit but before pressing the
Store key?
•
Edit the data and press the Store key once.
No
downloads
have
occurred.
•
Edits to data are permanently stores at
power down. Was the time from power
OFF to power ON less than six
seconds?
•
Wait six seconds or more before turning
power OFF after editing data.
Inverter data is
not correct.
A download
to the
inverter was
attempted.
•
Was the power turned OFF within six
seconds after the display changed from
REMT to INV?
•
Copy data to the inverter again, and keep
power ON for six seconds or more after
copying.
True for
certain
parameters.
•
Is the inverter in Run Mode? Some
parameters cannot be edited during
Run Mode.
•
Put inverter in Stop Mode (press the
Stop/reset key). Then edit the parameter.
A parameter
will not change
after an edit
(reverts to old
setting).
True for all
parameters.
•
If you’re using the [SFT] intelligent input
(software lock function)
is the [SFT]
input ON?
•
Change the state of the SFT input, and
check the B_31 parameter (SFT mode).
Monitoring Trip Events, History. & Conditions
Fault Detection and Clearing
The microprocessor in the inverter detects a variety of fault
conditions and captures the event, recording it in a history
table. The inverter output turns OFF, or “trips” similar to the
way a circuit breaker trips due to an over-current condition.
Most faults occur when the motor is running (refer to the
diagram to the right). However, the inverter could have an
internal fault and trip in Stop Mode. In either case, you can
clear the fault by pressing the Stop/Reset key.
