TECHNICAL NOTE
(j) NOT & C phase pulse method
The movement starts at the approach speed, and moves to the stroke limit in a negative direction. When
the NOT signal is detected, the movement is reversed and the speed is changed to the creep speed. When
C phase pulse is detected in reversing after the NOT signal is passed the final positioning is performed.
The machine coordinate system is established with the position to be the HOME
.
The amount of the movement from C phase pulse is set in the final travel distance for homing and the
positioning speed is set in the rapid feed speed.
When the OT signal is detected while moving at the positioning speed, it becomes OT alarm.

Error
TRAVSPD Speed of rapid
feed Traverse speed in count/second.
0-Max speed (ML3**12)
Moving direction follow the sign of the OFFSET.
APRSPD Approach speed Not used
CRPSPD Creep rate Creep speed in count/second.
0-Max speed (ML3**12)
The movement direction is in positive.
OFFSET Offset value Final moving distance. And the position will
be this value. If the value is positive, the
final moving is in the same direction of
homing. If it is negative the final moving will
be in the opposite of homing
