SECTION 4—PROGRAMMING
ANGLE SETTINGS
The SSC-1500 press control has an angle settings screen that is used to program the single stroke top stop, continuous top stop, auto up (holding),
and light curtain mute angles.
SINGLE STROKE TOP-STOP ANGLE
The single stroke top-stop angle is the angle at which the control gives the signal to stop the press at TDC (top dead center) while in the
Single
Stroke
mode of operation. In most cases, you will need to adjust this setting, since the factory default of 330° may stop your press beyond TDC. A
good angle to start with is 270°. If the press stops before TDC, a higher single stroke top-stop setting is required. Add the number of degrees the
machine stopped short of TDC to the single stroke top-stop setting. If the press stops beyond TDC, a lower single stroke top-stop setting is required.
Subtract the number of degrees the machine went over TDC from the single stroke top-stop setting.
CONTINUOUS TOP-STOP ANGLE
The continuous top-stop angle is the angle at which the control gives the signal to stop the press at TDC, when the top-stop palm button is pressed
while in the
Continuous
mode of operation. It is also used when a user input that is programmed to top stop activates.
The continuous top-stop angle applies only when the press has a constant speed drive, or has a variable speed drive that is run at only one speed.
If your press has a variable speed drive that is run at more than one speed, please refer to the variable speed top-stop settings on page 59.
In most cases, you will need to adjust this setting, since the factory default of 330° may stop your press beyond TDC. A good angle to start with
is 270°. If the press stops before TDC, a higher continuous top-stop setting is required. Add the number of degrees the machine stopped short
of TDC to the continuous top-stop setting. If the press stops beyond TDC, a lower continuous top-stop setting is required. Subtract the number of
degrees the machine went over TDC to the continuous top-stop setting.
AUTO UP (HOLDING) ANGLE
The auto up (holding) angle is the angle beyond which the operator no longer needs to depress the palm buttons or foot switch to finish the cycle in
progress. It applies only when the press is being run in the
Single Stroke
mode of operation. If the actuating means is released before the auto up
angle is reached, the machine will stop. This angle can be changed, but should be programmed so the actuating means must be held depressed
during the entire hazardous portion of the stroke.
THE LIGHT CURTAIN MUTE ANGLE
The light curtain mute angle is the angle beyond which the light curtain is no longer active. This means that once the light curtain mute angle is
reached, the machine will not stop if the light curtain beams are interrupted. This angle can be changed, but should be programmed so the light
curtain is muted only during the nonhazardous portion of the stroke.
