FX2N-1PG-E positioning
Fig. 4-27: Program example (1)
The forward and reverse rotation limit switches must be wired so that they are turned ON by default (Nor-
mally closed contacts).
When these limit switches turn OFF (due the workpiece going out-of-bounds), M2 or M3 will turn ON and
cause the pulse operation to stop.
