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. This is the number of degrees per 100 RPM.
Ac / RPMc x 100 = # ° / 100 RPM
Example: Calculating the Auto Advance Constant for a Pilot Release Cam
Your slowest speed is 50 RPM and the pilot release angle at that speed is 100 ° .
Your fastest speed is 100 RPM and the pilot release angle at that speed is 75 ° .
Subtract 50 RPM from 100 RPM: 100 – 50 = 50
Subtract 75
° from 100 ° : 100 – 75 = 25
Divide the difference in angles by the difference in RPM, and multiply this by 100:
25 / 50 x 100 = 50
Your advance constant is 50
° / 100 RPM
.
Setting Auto Advance Constants and Slow RPM
To set the auto advance constants and slow RPM value, do the following:
1.
Select AUTO ADVANCE on the Main Initialization Menu to access the Auto Advance
Menu (see Figure 4-9).
2.
With the highlight bar on ADVANCE CONST. 1, press ENTER. The Numeric Entry
window (see Figure 3-6, page 3-4) displays.
3.
Key in a value (maximum is 500) in the Numeric Entry window, using the numeric keypad
or the Up (

) and Down (

) cursor keys, then press ENTER.
4.
Repeat steps 2 and 3 for ADVANCE CONST. 2 (maximum value is 500) and SLOW RPM
(maximum value is 2000).
5.
When you are done, press RESET to return to the Main Initialization Menu.
If either stopping angle occurs after 0 ° (or 360 ° ), then add 360 ° to the angle. For instance,
if the press stops at 12 ° , the stopping angle is actually 12 ° +360 ° or 372 ° .
AUTO ADVANCE IS ADJUSTABLE
SmartPAC 2 allows you to adjust Auto Advance and Slow RPM settings in Initialization
mode while the press is running
.
The angle at which an Auto Advance cam turns on is
shown in the upper right corner of the screen under the caption PRESS ANGLE, enabling
you to see the effect of different settings.
