2.3.2 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.)
(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
To reset the inverter by operation panel operation, following these steps.
1. Press the STOP key and make sure that
is displayed.
2. Pressing the STOP key again will reset the inverter if the cause of the trip has already been eliminated.
☆When any overload function [
: inverter overload, : motor overload, : braking resistor overload] is active, the
inverter cannot be reset by inputting a reset signal from an external device or by operation panel operation before the virtual
cooling time has passed.
Virtual cooling time …
: about 30 seconds after the occurrence of a trip
: about 120 seconds after a occurrence of a trip
: about 20 seconds after a occurrence of a trip
☆In case of a trip due to overheating (
), the inverter checks the temperature within. Wait until the temperature in the inverter falls
sufficiently before resetting the inverter.
[Caution]
Tuning the inverter off then turning it on again resets inverter immediately. You can use this mode of resetting if there is a need to
reset the inverter immediately. However, that this operation may damage the system or the motor if it is repeated frequently.
