15. ABSOLUTE POSITION DETECTION SYSTEM
(c) ABS data transfer program for X axis
This sequence program example assumes the following conditions:
Parameters of the A1SD75-P1 (AD75-P1) positioning module
1) Unit setting :3
pulse (PLS)
2) Travel per pulse :1
1 pulse
To select the unit other than the pulse, conversion into the unit of the feed value per pulse is
required. Hence, add the following program to the area marked (Note) in the sequence program:
