This sequence program example assumes the following conditions:

Parameters of the A1SD71-S2 (AD71) 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 command value per pulse is required. Hence, add the following program to the area marked Note in the sequence program.
