[ m ] Home LS Signal Method (OW††3C = 15)
Travel is started at the creep speed in the direction specified by the sign of the creep speed. When the
rising edge of the home signal is detected, positioning is performed at the positioning speed. When
positioning has been completed, a machine coordinate system is established with the final position as
the zero point.
The moving
amount after the home signal is detected is set in the Home Offset. The positioning
speed is set in the Speed Reference Setting. 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 home
signal. If an OT signal is detected during positioning speed operation, an OT alarm will occur.
