8.

Set the flywheel speed to the highest speed range. Repeat Steps 4 and 5.

9.

Repeat steps 3, 4, 5, 6, 7, and 8 with the press in Continuous mode. In this mode the four top stop
angles shown on the line labeled Continuous (line 6 above) affect the stopping characteristics of the
press. These parameters are used during this portion of the calibration process. The Top Stop button
should be used to cause the press control to initiate a stop on top.

Section 5.1.1.2 Single Speed Presses, Link Standard

Single speed presses require a calibration procedure similar to that of variable speed machines be performed
when the press control is installed. Since the press operates at only one speed, the four program speeds and
top stop positions must be programmed to the same value. The suggested top stop calibration procedure is
as follows:

1.

Switch to the PROG position and enter the speed at which the press is to be operated into all four
speed settings.

A cursor appears in the PROG mode to indicate which parameter is to be changed, and is positioned
with the arrow keys (see section on Operator Terminal).

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.

Switch to the RUN position and operate the press.

4.

Adjust the top stop angle until the press comes to rest at top dead center. All four top stop angles
for this stroking mode must be set to the same value. Changes can be made only in the PROG 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.

5.

Repeat steps 3 and 4 with the press in Continuous mode. In this mode the four top stop angles
shown on the line labeled Continuous (line 6 above) affect the stopping characteristics of the press.
These parameters are used during this portion of the calibration process. The Top Stop button should
be used to cause the press control to initiate a stop on top.

Section 5.1.2 Top Stop Calibration, Link High Speed

The menu shown in Figure 5.4 allows the press control's top stop angle to be calibrated at two speeds (low
and high) that describe the operating range of the machine. These calibration parameters are used to
calculate the coefficients to a nonlinear equation that models the stopping characteristics of the press and
entries that do not yield a valid equation are rejected. It should be noted that speed advance is based on the
speed of the crankshaft and not the flywheel.
