2: DEC 1 + Zero Signal
In place of the Phase-C pulse of the DEC 1 + Phase-C pulse method, this method uses the
zero signal to return to the zero point.
3: Phase-C Pulse
This method uses just the Phase-C pulse of the Servomotor to return to the zero point in
machines that are not equipped with deceleration LS and other capabilities.
