11. Troubleshooting Tips

The

motor

will

not run.

The
inverter
outputs
U,V and
W are not
supplying
voltage.

Inverter
outputs
U,V,W are
supplying
voltage.

Symptom/condition

Probable Cause

Countermeasure

Is power being supplied to

terminals L1, L2
If so, the power lamp should
be on.

Is there an error code

¡¡

displayed?

Check terminals L1, L2

then U, V, and W

Turn on the power supply

or check fuses.

Are the signals to the intelli-

gent input terminals correct?

Is the Run Command active?

Is the[FW] terminal (or [RV]

connected to CM1(via switch,
etc.)

Has the frequency setting

for F01 been set greater than
zero?

Are the control circuit term-

inals H, O, and L connected
to the potentiometer?

Is the motor load too heavy?

Is the motor locked?

Reduce load, and test the

motor independently.

Is the RS(reset) function

or FRS(free-run stop)

function on?

Turn off the command(s)

Set the parameter for F01

to a safe, non-zero value.

If the potentiometer is the

frequency setting surce,
verify voltage at"O"

Verify the terminal functions

for C01-C06 are correct.

Turn on Run Command

Supply 24V to [FW] or [RV]

terminal, if configured.
(Terminal mode selection)

Press the Func key and

determine the error type.
Then clear the error(Reset).

Is the frequency command

source A01 parameter setting

correct?

Is the Run command source

A02
correct?

parameter setting

Make sure the parameter

A01

setting correct?

Make sure the parameter

A02

setting correct?
