TROUBLESHOOTING

6.1 Before Proceeding with Troubleshooting

If any of the protective functions have been activated, first remove the cause. Then, after
checking that the all run commands are set to off, reset the alarm. Note that if the alarm is reset
while any run commands are set to on, the inverter may supply the power to the motor which may
cause the motor to rotate.

Injury may occur.

- Even though the inverter has interrupted power to the motor, if the voltage is applied to the

main circuit power input terminals L1/R, L2/S and L3/T (L1/L and L2/N for single-phase
voltage input), voltage may be output to inverter output terminals U, V, and W.

- Some electric charge may remain in the DC bus capacitor even after the power is turned off.

Therefore, it may take some time until the DC link circuit voltage reaches a safe level. Before
touching the circuit, wait for at least five minutes after the power has been turned off and
check that the DC voltage between main circuit terminals P (+) and N (-) is less than +25
VDC using a multimeter.

Electric shock may occur.

Follow the procedure below to solve problems.
(1) First, check that the inverter is correctly wired, referring to Chapter 2, Section 2.3.5 "Wiring for

Main Circuit Terminals and Grounding Terminals."

(2) Check whether an alarm code is displayed on the LED monitor.

If any problems persist after the above recovery procedure, contact the Company where you
purchased the inverter or contact IMO.
