Jog Your Machine
Jogging your machine is similar to operating it in set output; percent output
values are applied to your four QDC module outputs in order to obtain the
desired motion. The jog configuration block (JGC) allows you to set up
jog parameters for your QDC outputs for close and open clamp jogging
and advance and retract jogging of the ejector.
Although the QDC module may not be directly controlling your machine’s
screw or injection cylinder jogs, your hydraulics may require valves
connected to your Clamp and Ejector QDC outputs to go to a certain
position to assure proper screw and inject cylinder jog functions. The
QDC jog configuration block allows you to set up these indirect jog values.
This chapter describes how to:
configure all jog block values necessary to jog your clamp and ejector
test these jog values and make changes if necessary
configure values which may indirectly affect your machine’s screw and
inject cylinder jogs
