13.2 Restoring the inverter from a trip
Do not reset the inverter when tripped because of a failure or error before eliminating the cause. Resetting the
tripped inverter before eliminating the problem causes it to trip again.
The inverter can be restored from a trip by any of the following operations:
(1) By turning off the power (Keep the inverter off until the LED turns off.)
Note: ⇒ See section 6.17.3 (inverter trip retention selection H) for details.
(2) By means of an external signal (Short circuit between RES and CC on terminal board → Open)
(3) By operation panel operation
(4) By inputting a trip clear signal from a remote input device
(Refer to the remote input device operating manual for details.)
To reset the inverter by operation panel operation, follow these steps.
1. Press the key and make sure that ENT is displayed.
2. Pressing the key again will reset the inverter if the cause of the trip has already been eliminated.
+ In case of a trip due to overheating (QJ), the inverter checks the temperature within. Wait until the
temperature in the inverter falls sufficiently before resetting the inverter.
[Caution]
Turning the inverter off then turning it on again resets the inverter immediately. You can use this mode of
resetting if there is a need to reset the inverter immediately. Note, however, that this operation may damage
the system or the motor if it is repeated frequently.
