[ c ] DEC1 + ZERO Signal Method (OW
Operation after Zero Point Return Starts
Travel is started at the zero point return speed in the direction specified in the parameters.
When the rising edge of the DEC1 signal is detected, the speed is reduced to the approach speed.
When the rising edge of the ZERO signal is detected after passing the DEC1 signal at the approach
speed, the speed is reduced to the creep speed and positioning is performed.
When the positioning has been completed, a machine coordinate system is established with the final
position as the zero point.

Set the travel distance from the point where the ZERO signal is detected
after passing the DEC1 signal.
Home Offset
If the sign is positive, travel will be toward the zero point return direction; if
the sign is negative, travel will be away from the zero point return direction.
