Operation after Zero Point Return Starts
Travel is started at the approach speed in the direction specified by the sign of the approach speed.
When the rising edge of the home signal is detected, the speed is reduced to creep speed.
When the first phase-C pulse is detected after the falling edge of the home signal, the positioning is
performed at positioning speed.
When the positioning has been completed, a machine coordinate system is established with the final
position as the zero point.
The moving amount after the phase-C pulse is detected is set in the Home Offset. The positioning
speed is set in the Speed Reference.
If an OT signal is detected during approach speed operation, an alarm will not occur, the direction
will be reversed, and a search will be made for the home signal.
If an OT signal is detected during positioning speed operation, an OT alarm will occur.

13: POT Only Method
Set the positioning speed to use after detecting the POT signal. The sign is
ignored.
The travel direction will depend on the sign of the Home Offset.
Set the speed to use when starting a zero point return.
Add a sign so that the travel direction will be positive.
Set the travel distance from the point where the POT signal is detected.
The travel direction will depend on the sign.
