Check power supply voltage.

⋅

Make sure terminal screws are tight.

Use rectifier type voltmeter to test. Voltage

output to output terminals U, V, W correct?

Turn OFF power supply, then turn ON again.

Motor locks due to excessive load?

Reduce the load and release the lock.

Motor does not rotate. Fault displayed in digital operator display?

Check Table 29.

FWD or REV run command entered? (only for

REMOTE operation)

Check the wiring.

Speed setting voltage entered?

(Only for REMOTE operation)

⋅

Correct the wiring.

⋅

Check speed setting voltage.

Speed reference selection (b1-01), run com-

mand selection (b1-02) correct?

Input the correct set value.

Motor rotation

reverses

Wiring of terminals U, V, W correct?

Match wiring to the phase order of the motor

leads U, V, W.

reverses.

Correct the wiring.

Motor rotates, but

variable speed not

Wiring of speed setting circuit correct?

Correct the control circuit wiring.

variable speed not

available.

Load excessively large?

Reduce the load.

Motor ratings (number of poles, voltage)

correct?

Check motor nameplate specifications.

Motor speed too high

or too low.

Accel/decel speed change ratio for gears, etc.

correct?

Check speed changer (gears, etc.)

or too low.

Torque reference saturated?

Check the settings of U1-09 and L7-01 to L7-04.

Maximum speed set value correct?

Check the maximum speed set value (E1-06).

Load excessively large?

Reduce the load.

Motor speed not

stable during

operation.

Load variation excessively large?

⋅

Reduce the load variation.

⋅

Increase inverter and motor capacity.

operation.

Power supply open-phase?

Check the wiring.

Motor does not rotate
when the power sup-
ply is turned ON with
the operation com-
mand entered.

After switching between LOCAL/REMOTE,
the setting of (b1-06) correct?

Set b1-06=1.
