To calibrate a rotary slide adjust system:
a)
Make sure the upper and lower limit settings have been set correctly in the slide
configuration screen of Figure 4.6.
b) Press the CALIBRATE SLIDE softkey in the slide configuration screen of Figure 4.6.
c)
A screen will appear with a warning that calibrating the slide should not be undertaken
without first reading this manual. Press the CONTINUE SLIDE CAL. softkey to
continue the calibration process or EXIT to return to slide configuration.
d)
The next screen will give instructions for positioning the slide at bottom dead center.
This is usually accomplished by stroking the press in Inch mode to position the press
slide at the bottom of the stroke. This is not adjusting the slide shut height to its bottom
position. This is moving the slide to the bottom of its stroke. This is bottom dead center,
which is usually equivalent to a crankshaft position of 180
°. This screen also warns
that this is the last chance to abort the calibration procedure without destroying the
results of a previous calibration. If this is an initial calibration, this warning does not
apply, because there was no previous calibration.
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.
NOTE: It us absolutely critical to set the upper and lower limits correctly
before calibrating a rotary slide adjust system. The calibration
process uses this information to map the turns from the dual resolver
into measurement space of the slide. If the upper and lower limits
are not set correctly, the system may fail to calibrate.
WARNING! Since the slide adjust configuration procedure requires
measurements of the space between the press slide and bed or
bolster, this procedure must be preformed 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.
