WARNING: After calibration always check for proper operation of the slide adjust
system as wiring or transducer faults could cause an invalid calibration.
Bad measurements could result in damage to the machine and tooling,
and can cause injury or death.
transducer is used) must now be set. This value is listed on the transducer model plate. Press the
“CONTINUE SLIDE CAL.” softkey to continue the calibration process or “EXIT” to return to
slide configuration.
f) Finally, the “Calibration Point” must be set. The slide should be taken to bottom dead center
(180 degrees) and the shut height should be measured. Without moving the slide that
measurement should be entered here. This tells the system what the current shut height is. Press
the “CONTINUE SLIDE CAL.” softkey.
g) The slide system should now be calibrated. Check for proper operation by running the slide up
near the top of the adjustment range and checking the slide position reported. Note that linear
transducers are repeatable but not absolutely accurate. This means the reported slide position
may differ from the measured position by as much as .030". Repeat this process with the slide
near the bottom of the adjustment range.
Section 4.2.2.2 Calibrating Rotary Slide Adjust Systems
After setting the parameters in the previous section, the rotary slide system must be calibrated before it
can be used.
IMPORTANT! Configuring/calibrating the slide adjust module should only be done with no
dies installed in the press and, for presses equipped with slide counterbalance
systems, should proceed only after the counterbalance is properly adjusted to
offset the weight of the slide. If counterbalance pressure is too low, bearing
clearances will cause shut height measurements made during calibration to be
too small.
WARNING! Since the slide adjust configuration procedure requires measurement of
the space between the press slide and bed or bolster, this procedure must
be performed with no dies or tooling in the press to prevent the possibility
of a point of operation or pinch point injury to personnel making the
measurement. Failure to heed this warning may result in serious injury
or death.
To calibrate a rotary slide adjust system:
a) Make sure the upper and lower limit settings have been set correctly in the slide configuration
