generated the correct stopping curve.
3. With the Program/Run switch in the RUN position, select Continuous mode.
4. The same top stop calibration procedure as described above can be performed for Continuous stroke
modes (area 2 in Fig. 5.4). It should be possible to use the manual stroke mode settings as a starting
point and then make adjustments at the low and high speeds to compensate for different stopping
characteristics in continuous stroking modes. If Continuous mode allows the flywheel speed to be
set higher than Single Stroke, after calibrating at the first two speeds, set the speed pot to the
maximum stroking speed. Since the press control is operating with a calibrated stopping curve, the
calculated speed and top stop angle (area 3 of Fig. 5.4) should indicate the actual values for this
speed. Press the top stop button and enter the calculated speed and stop angle from the last stroke
into the high speed column for Continuous stroke modes. It may then be necessary to adjust this high
speed top stop position in order to achieve the desired top of stroke.
Section 5.1.2.2 Single Speed Presses, Link High Speed
Single speed presses can be calibrated by setting the top stop position for both low and high speed to the
same value. This prevents the press control from calculating a stopping angle based on press speed, and
instructs the control to initiate a top stop at the angle programmed regardless of speed. This stopping angle
can be set differently for manual stroking modes and continuous stroking modes (see Figure 5.4).
Section 5.1.3 Stop Angle (Setup Mode)
This programmed angle is used ONLY in the Setup/Stop Time Test mode, and is limited to between 2 and
358 degrees. It is used at all speeds, and is intended to provide a repeatable stop signal with which to
measure the stopping time of the press and to aid in the setup of mechanically driven feeds. This angle can
be changed only in the PROG mode by positioning the cursor onto this parameter and using the numeric
keypad. As indicated above this angle is used only in the Setup/Stop Time Test mode, and is limited to
between 2 and 358 degrees.
Section 5.2 Machine Parameters
The menu shown in Figure 5.5 shows the machine parameters that can be changed by the user. Changes can
be made only in the PROG mode. The arrow keys are used to position the cursor onto the parameter which
is to be change.
