will always say “channel 1,” “channel 2,” etc. This is so that you always know which
channel you are naming. However, the actual channel names will appear in Program and
Run modes along with their respective channel numbers.
AUTO ADVANCE and Slow RPM
(INITIALIZATION – AUTO ADVANCE)
You use this choice in the Initialization menu to set auto advance constants for up to two
press auto advance functions. Some cam functions that may use auto advance are top stop,
feed advance, pilot release, advance slide, and part lube.
This feature works best on presses
that have speed ranges of several hundred to over a thousand strokes per minute.
Advance constant is equal to the number of degrees of advance per 100 RPM increase in
press speed…
Advance Constant = # degrees /100 RPM
To calculate the auto advance constant for top stop, follow these steps:
1. Determine the fastest press speed (
RPMa
) and the angle at which the press stops at this
speed (
Aa
).
2. Determine the slowest press speed (
RPMb
) and the angle at which the press stops at this
speed (
Ab
).
NOTICE
If either stopping angle occurs after 0° (or 360°), then add 360° to the angle. For instance,
12° would really be 12°+360° or 372°.
3. Subtract the two angle values. We will call this result “
Ac
.”
Aa – Ab = Ac
4. Subtract the two press speeds. We will call this result “
RPMc
.”
RPMa – RPMb = RPMc
5. Divide
Ac
(the difference between the angles) by
RPMc
(the difference between the
press speeds), and multiply that value by 100. That is the number of degrees per 100
RPM.
Ac x 100 = # ° / 100 RPM
RPMc
Example for calculating the auto advance setting:
Your slowest speed is 50 RPM and the stopping angle is at 325°.
Your fastest speed is 100 RPM and the stopping angle is at 350°.
Subtract 100 RPM from 50 RPM…
100 – 50 = 50
Subtract 350° from 325…
350 – 325 = 25
Divide the difference in angles by the difference in RPM, and multiply this by 100. 50° is
your advance constant.
25 / 50 x 100 = 50.00
50° / 100 RPM
