Restoring The Inverter From A Trip - Toshiba TOSVERT VF-S11 Instruction Manual

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) Refer to 6.15.3 (inverter trip retention selection
(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.

the system or the motor if it is repeated frequently.

When any overload function [
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 (
