Figure 4.12 Speed Adjusted Top Stop Calibration Menu


There are 7 items indicated on the Speed Adjusted Top Stop Calibration Screen, which is used to
calibrate top stop for both variable speed presses and fixed speed presses. These items are:

1. Low Speed SPM. This is a setting that must be entered for the lowest strokes/min for a variable

speed press. For a fixed speed press, both the Low Speed SPM and the High Speed SPM of item 3
will be entered as the nominal speed of the press in strokes/min.


2. Low Speed Degrees Before Top Dead Center (0

0

). This is an angle setting that must be entered to

initiate a stop for a variable speed press stroking at the Low Speed SPM that will result in stopping
within a couple of degrees of Top Dead Center. For a fixed speed press, the number entered here
will be the same as for High Speed Degrees Before top Dead Center in item 4.

3. High Speed SPM. This is a setting that must be entered for the highest strokes/min for a variable

speed press. For a fixed speed press, both the High Speed SPM and the Low Speed SPM of item 1
will be entered as the nominal speed of the press in strokes/min.


4. High Speed Degrees Before Top Dead Center(0

0

). This is an angle setting that must be entered to

initiate a stop for a variable speed press stroking at the High Speed SPM that will result in stopping
within a couple of degrees of Top Dead Center. For a fixed speed press, the number entered here
will be the same as for Low Speed Degrees Before top Dead Center in item 4.


5. Speed At Stop Initiation. This is a measured speed of the crank or eccentric at the angle that a stop

signal intended to stop the press at TDC is initiated. It automatically appears each time the press
strokes and intended to aid in the automatic top stop calibration process for variable speed presses.
You cannot enter a setting for this item.
