Jog Your Machine
Chapter 5
5-5
Take time now to develop ladder logic (independent of Pro-Set 600
software) to jog the ram (screw), clamp, and ejector. You may need to
monitor switches on your operator control panel, and set corresponding
command bits.
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.A and 5.B identify
command and status bits for jogging the ram (screw), clamp, and ejector.

We provide a programming example (Figure 5.1) of 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 ram (screw), clamp, and/or ejector travel hydraulically when
you command the QDC module to jog in reverse.
