Reset Method of Protective Function
Resetting the Inverter
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.
앫
Using the operation panel, press the STOP/RESET key to reset the inverter.
(This may only be performed when a fault occurs.)
앫
Switch OFF the power once, then switch it ON again after the indicator
of the operation panel turns OFF.
앫
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.)
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.
