some information needs to be gathered.
A GEMCO 952 series linear transducer is mounted on the press slide. From the name plate on the
transducer, we find that the wire speed is 9.219 microseconds per inch. Remember that some transducer
manufacturers may call this “gradient” but the value must always represent microseconds per inch.
From the nameplate on the press or the press manual, we find that the minimum shut height is 12.500
inches and the maximum shut height is 16.000 inches.
Now we go to the “Auto Sets” screen and with the RUN/PROG switch in PROG hit the “CONFIGURE”
softkey. After typing the configuration code, we press the “CONFIGURE SLIDE” softkey.
Since the slide adjust system is wired in at “SS1", if the slot reported on the screen in not already
“AS1", we hit the “NEXT SLIDE SLOT” softkey until it is. The hardware detected should be “Linear
Transducer”.
The first thing we must configure is the “Name” of the system. The cursor should already be on the
“Name” line so we check to see if the name is already “Slide Adjust #1". If not, the “CHANGE
NAME” softkey allows us to cycle through the systems.
During initial slide setup, the “Mode” of the slide needs to be set to “OFF”. Moving the editing cursor
to the mode parameter, we hit the “CHANGE MODE” softkey until the mode reads “OFF”.
Before we set anything further, we need to choose the units for the slide system. Moving the editing
cursor to the “Shut Height Units” parameter, we use the “CHANGE UNIT” softkey to set the units to
inches for this example. Note that this sets the units for all other shut height position or distance
parameters on this screen and during calibration. After calibration, the units can be changed, if desired.
The “Upper Limit” and “Lower Limit” we set to 16.000 inches and 12.500 inches respectively. When
the mode if the system is “OFF”, these limits are not enforced. This allows us to check the operation of
the mechanical limit switches.
The “Tolerance”, “Pulse Distance”, “Pulse Time”, and “Lock Time” are left at .004, .010, .03, and 0
respectively - the default values. We may find these have to be changed later on.
We find that the magnet on the linear transducer travels toward the control head (where the cable comes
out) as the press is going up. We need to know this for calibration.
Before calibrating the slide, we MUST make sure the slide is properly counterbalanced, if a
counterbalance is used on our press. If the slide is not properly counterbalanced, the slide calibration
will be flawed because clearances will not be taken up by the counterbalance.
Now we press the “CALIBRATE SLIDE” softkey to perform the actual slide calibration as described in
section 4.2.2.1 using the wire speed from the transducer nameplate (9.219 in this example) and an
orientation of 0.
After calibration, the “Present Position” field in the slide configuration screen should display the
number we just entered for the calibration position to the nearest thousandth. In other words, if we had
entered 14.074 inches for our calibration position, the present position should read 14.073 to 14.075
