6.2 Reset

There are three methods to reset the AC motor drive after solving the fault:

1.Press STOP/RESET key on keypad.

2.Set external terminal to “RESET” (set one of Pr.4-04~Pr.4-08 to 06) and then set to be ON.

3.Send “RESET” command by communication.

NOTE

Make sure that RUN command or signal is OFF before executing RESET to prevent damage or

personal injury due to immediate operation.
