Word 1 in the Dynamic Command block (DYC01) is used to enable and
disable individual jogs. Word 1 in the System Status block (SYS01) may
also be used to monitor the QDC module’s reaction to jog commands.
Below are two quick cross-reference tables identifying the jog enable and
status bits for the clamp and ejector:

Take time now to develop ladder logic (independent of Pro-Set 600
software) to jog the clamp and ejector with the QDC module. You need to
monitor switches on your operator control panel, and set corresponding
command bits.
We provide a programming example (Figure 5.1) for jog control for
instructional purposes only. Your application-specific programming may
vary significantly from this example.
Important: You may also need to develop ladder logic that changes the
direction of clamp and ejector travel hydraulically when you command the
QDC module to jog in reverse.
