Table 6 Motor Faults and Corrective Actions
Fault Check point Corrective action
Motor does not rotate. Power supply voltage is applied to
power supply terminals L1 (R), L2 (S),
and L3 (T). (Check that charge lamp is
on.) Turn on the power supply.
Turn off the power supply and then on
again.
Check power supply voltage.
Voltage is output to output terminals
T1 (U), T2 (V), and T3 (W). Turn off the power supply and then on
again.
Load is excessively large. (Motor is
locked.) Reduce the load. (Release the lock.)
Fault is displayed. Check according to Par. 1.7.1
FWD or REV run command is entered. Correct the wiring.
Frequency setting signal is entered.
Operation (method selection) mode
setting is proper. Check the operation method selection
mode by using the digital operator.
Motor rotating direction is
reversed. Wiring of output terminals T1 (U), T2
(V), and T3 (W) is correct. Match them to the phase order of mo-
tor T1 (U), T2 (V), and T3 (W).
Wiring of FWD and REV run signals is
correct. Correct the wiring.
Motor rotates but variable
speed is not available. Wiring of frequency setting circuit is
correct. Correct the wiring.
Load is not excessively large. Reduce the load.
Motor r/min is too high
(low). Motor ratings (number of poles, volt-
age) are proper. Check the specifications and name-
plate.
Accel/decel ratio by speed changer
(gears, etc.) is correct. ---
Maximum frequency set value is cor-
rect. Check the maximum frequency set
value.
Voltage between motor terminals is
not excessively reduced. Check the base frequency.
r/min is not stable during
ti
Load is not excessively large. Reduce the load.
g
operation.
Load variation is not excessively large. Reduce the load variation.
Increase the inverter or motor capac-
ity.
