Do this only after writing all direct and assisted ladder logic for controlling
clamp and eject jogs.
Jog your clamp and/or ejector in forward and retract directions.
Experiment with values you entered in the jog configuration block (JGC)
until you obtain the desired jog operation.
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.
If You Observe This Condition: Then Make This Adjustment:
Rough jerky acceleration or deceleration
(Hammering hydraulics)
1) Decrease jog pressure
2) Decrease jog setpoint
Sluggish acceleration or deceleration 1) Boost jog pressure
