Use Pulse Output Function
Overview
Sending pulse output in direction control mode.
Turn ON Enable input at R4.0 and Start input. Pulse output starts at
R2.8 and R2.9 (PLS0).
When direction input at R4.2 is ON, pulse changes to reverse direction.
Timing Diagram
Pulse output changes in reference to the input status of each signal as
illustrated below.

Output of reverse pulse
Pulse output starts when edge rise of Start signal is
detected while Enable signal is ON.
When direction changes, 1 pulse
is deleted.
