[ e ] C Pulse Only Method (OW
Operation after Zero Point Return Starts
Travel is started at the creep speed in the direction specified by the sign of the creep speed. When the
rising edge of the phase-C pulse is detected, positioning is performed at the 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 creep speed operation, an OT alarm will not occur, the direction
will be reversed, and a search will be made for the phase-C pulse.
If an OT signal is detected during positioning speed operation, an OT alarm will occur.
