Jog Your Machine
Chapter 5
5-9
If your hydraulics require it, take time now to develop ladder logic
(independent of Pro-Set 600 software) so the QDC module (in inject mode)
can assist jogging the clamp and ejector. Otherwise, omit the rest of this
chapter.
Use word 1 in the dynamic command block (DYC01) to enable and disable
individual jogs. Use word 1 in the system status block (SYS01) to monitor
the QDC module’s reaction to jog commands. Tables 5.C and 5.D identify
command and status bits for jogging the clamp and/or ejector.

We provide a programming example (Figure 5.2) of assisted 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/or ejector travel hydraulically when you command
the QDC module to retract the clamp and/or ejector.
