If configured, the Motor Speed Adjust screen can be accessed from this screen in order to change the
stroking speed of the press (see Section 4.7).
Section 5.1.1.1 Variable Speed Presses, Link Standard
Variable speed presses require a calibration procedure be performed when the press control is installed. This
process uses the top stop characteristics of the press at four programmed speeds. The suggested top stop
calibration procedure is as follows:
1.
Switch to the PROG position and enter the four speeds at which the top stop position will be
calibrated. These speeds, shown left to right, correspond to the following formulas:
Left
Lowest operating speed of the machine.
Next
Lowest speed + (1/3 (highest-lowest)).
Next
Lowest speed + (2/3 (highest-lowest)).
Right
Highest operating speed of the machine.
A cursor appears in the PROG mode to indicate which parameter is to be changed, and is positioned
with the arrow keys.
2.
Select Single Stroke mode. In this mode the four top stop angles shown on the line labeled Single
(line 5 above) affect the stopping characteristics of the press. These parameters are used during this
portion of the calibration process.
3.
Set the flywheel speed to the lowest range.
4.
Switch to the RUN position and operate the press.
5.
Adjust the top stop angle until the press comes to rest at top dead center. Changes are made by
selecting the PROG mode and positioning the cursor onto the stop angle for this speed and present
stroking mode.
NOTE:The new values do not become written into the press control's memory until the Program/Run switch
is returned to the RUN position.
NOTE:A top stop angle MUST be equal to or greater than the stop angle for the next higher speed range,
or it will be rejected when returned to the RUN position. To program a new angle, the higher speed's
angle may have to be changed also.
6.
Set the flywheel speed to the next speed range approximately 1/3 of the way between lowest and
highest programmed speeds. Repeat Steps 4 and 5.
7.
Set the flywheel speed to the next speed range approximately 2/3 of the way between lowest and
highest programmed speeds. Repeat Steps 4 and 5.
