7.1 Reset Method of Protective Function

The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of
the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.
Inverter recovers about 1s after reset is cancelled.
Three different methods can be used to reset an inverter.
Using the operation panel, press the STOP/RESET key to reset the inverter.
(This may only be performed when a fault occurs.)
Switch OFF the power once, then switch it ON again after the indicator of the operation panel turns OFF.
Turn ON the reset signal (RES) for more than 0.1 s. (If the RES signal is kept ON,
"Err." appears (flickers) to indicate that the inverter is in a reset status.)
NOTE
When a fault occurs during PLC function, turning ON of X51 signal can release fault without interrupting PLC function.
(Refer to FR-F700 PLC function programming manual.)
CAUTION
OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting inverter fault with the start
signal ON restarts the motor suddenly. This may cause injury.
