Making an Auto Advance Setting
The PROGRAM AUTO ADVANCE item on the Cam Channel Program Type Menu enables
you to program up to two cam channels as Auto Advance and to set On and Off angles for
those channels. Auto Advance cam settings automatically compensate for changes in press
speed, advancing cam timing as the speed of the press increases, delaying timing as speed
decreases. An Auto Advance cam channel is often used for Top Stop because it ensures that
the press will top-stop at the same angle regardless of varying press speeds. Auto Advance
settings are also used for feed, pilot release, lube, and other speed-sensitive applications.
To program an Auto Advance cam channel, do the following:
1.
Select PROGRAM AUTO ADVANCE on the Cam Channel Program Type Menu. The
Cam Channel Auto Advance Program screen, shown in Figure 5-51, displays.
2.
Set the AutoOn angle on the crank angle clock, using the Left (

) and Right (

) cursor
keys.
As you press the Left (

) cursor key, the On cursor moves counterclockwise around the
display, and the AutoOn angle value decreases. When you press the Right (

) cursor key,
the On cursor moves clockwise around the display, and the AutoOn angle value increases.
The precise AutoOn angle value is displayed in the window inside the clock display. In
Figure 5-51, the AutoOn angle is set to 288
°
.
You can program up to two Auto Advance output settings in Program mode. The first advance
constant set in Initialization mode controls the lowest-numbered Auto Advance channel in
Program mode. Likewise, the second advance constant controls the next numerically higher Auto
Advance channel. If channels 3 and 5, for example, are programmed as Auto Advance, channel 3
will use the first advance constant, channel 5 the second advance constant. See AUTO
ADVANCE and Slow RPM (Optional), page 4-12 for more information.
