TECHNICAL NOTE
(b) ZERO signal 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 the ZERO signal and finishes positioning.
The machine coordinate system is established with the position to be the HOME.
The amount of the movement from the ZERO signal 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 1: "ZERO signal" method 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
