13.2Restoring 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 6.1 4.2 (inverter trip retention selection ) for details.

(2)By means of an external signal [Short-circuiting of control terminals RST and CC open (Assignment of functions to input terminals is necessary)]

(3)By operation panel operation

(4)By inputting a trip clear signal from a remote input device

(Refer to the Communications Equipment User’s Manual for details.)

To reset the inverter by operation panel operation, follow 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,] 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 the occurrence of a trip

[Caution]

Turning the inverter off then turning it on again resets the inverter immediately. You can

13 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.

If the inverter trips because of overheating (), do not reset the inverter immediately but wait until the temperature in the inverter comes down, because its internal temperature is monitored.
