TECHNICAL NOTE
(c) DEC 1+ZERO signal method
The movement starts at the speed of the homing in the direction specified by the parameter.
When the rising edge of the DEC1 signal is detected, speed is decelerated to the approach speed.
Speed is decelerated to the creep speed at the rising edge of the ZERO signal after DEC1 is
passed at the approach speed, and final positioning is performed. 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 2: "DEC+ZERO signal" method is selected.
TIME Timer limit
setting Maximum time to complete the Homing, if timeout
then Error
TRAVSPD Speed of rapid
feed
Traverse speed in count/second.
0-Max speed (ML3**12)
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
