Do this only after writing all direct and assisted ladder logic for controlling
screw-rotate and ejector jogs.
Jog your ejector in forward and retract directions. Rotate the ram (screw)
by jogging. Experiment with values you entered in the jog configuration
block (JGC) until you obtain the desired jog operation.
If You Observe This Condition: Then Make This Adjustment:
Rough jerky acceleration or deceleration
(hammering hydraulics)
1) Decrease jog pressure
2) Decrease jog flow
Sluggish acceleration or deceleration 1) Boost jog pressure
You must download the JGC block to the QDC module each time you
change a value in the command block to implement the new value. Refer
to the download procedure outlined in chapter 4.
Jog the Ejector and
Rotate the Screw
