[ l ] INPUT & Phase-C Pulse Method (OW
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 INPUT signal is detected, the speed is reduced to the creep speed.
When the first phase-C pulse is detected after the falling edge of the INPUT 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 OT alarm will not occur, the direc-
tion will be reversed, and a search will be made for the INPUT signal.
If an OT signal is detected during positioning speed operation, an OT alarm will occur.
