Inverter Drive Control
Fig. 4-22: Program example (3)
The forward and reverse rotation limit switches must be wired so that they are turned ON by default (Nor-
mally closed contacts).
When either of these limit switches turns OFF (due to the workpiece going out-of-bounds), the inverter
operation will be stopped.
