TECHNICAL NOTE
(d) C phase pulse method
The movement starts at the approach speed in the direction specified by the parameter. Speed
is decelerated to the creep speed at the rising edge of C phase pulse, and 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 of homing.
When the OT signal is detected while in homing process, it becomes OT alarm.
Input Name Set content
EXECUTE Execution Block enable
REVERSE Direction
selection The direction of the homing.
0: Seek in forward
1: Seek in reverse
INPUT INPUT input Not used
AXIS Axis setting Axis number related to the block.
1～16
TYPE Home position
return method 3: "C phase pulsed system" is selected.
TIME Timer limit

Error
TRAVSPD Speed of rapid
feed Not used
APRSPD Approach speed Approach speed in count/second.
0-Max speed (ML3**12)
CRPSPD Creep rate Creep speed in count/second.
0-Max speed (ML3**12)
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
