Press
ENTER
when finished. After the correct security code has been
entered, the first VARIABLE SPEED TOP-STOP SETTINGS SCREEN will
be displayed. See Figure 4.54.
Use the

VARIABLE SPEED TOP-STOP SETTINGS
The variable speed top-stop settings screens are used to program the angles at which the control gives the signal to stop the press at TDC (top dead
center), when the top-stop palm button is pressed while in the
Continuous
mode of operation. This will ensure the press will stop at top, regardless
of the speed at which it is run. These settings also apply when a user input activates that has been programmed to top stop. These settings should
be used
only
if your press has a variable speed drive, and it is run at different speeds. If you have a constant speed press, or if you have a variable
speed drive but run it at only one speed, make sure this function is turned off.
HOW TO CALCULATE THE VARIABLE SPEED TOP-STOP SETTINGS
There are six locations to input your press’s speed and corresponding top-stop angle. In the first location, the slowest speed that you run the press
at should be input. The fastest speed that you run the press at should be input in the sixth location. The second through the fifth locations should
be input with speeds in even increments between your slowest and fastest speeds.
Once all six speeds are input, the corresponding top-stop angles can be set. Start with the first location; a good angle to start with is 270°. If the
press stops before TDC, a higher angle setting is required. Add the number of degrees the machine stopped short of TDC to the setting. If the press
stops beyond TDC, a lower angle setting is required. Subtract the number of degrees the machine went over TDC from the setting. Repeat this for
the rest of the angle settings.
