*1 Make sure that servo ON input is "OFF" when you return the input signals of safety inputs 1 and 2 to "ON." If an
error exists in this state, be sure to clear the error when both safety inputs 1 and 2 have returned to "ON" state.
If either safety input 1 or 2 is executed with "OFF", an error occurs immediately. Also, depending on the
execution timing, an Other Error (Error No. 99.9) may occur.
If this error (Error No. 99.9) occurs, turn OFF and then ON the power again.
