Feed Advisor
You select "Feed Advisor" when you want ProCam 1500 SFI to figure out the
acceleration rate and maximum run speed for you.
NOTE
Feed Advisor is not available with all servo feed models.
Feed Advisor is a convenience which saves you the time of calculating the acceleration rate
yourself. You need to enter feed length, feed arc (number of crankshaft degrees available to
fully feed the material), and press speed when using Feed Advisor. The acceleration rate
and run speed is calculated assuming the lowest acceleration rate to fully feed the material
by the end of the feed arc. When determining this rate, take into consideration the feed
initiate angle, which may be programmed as one of the cam timings in ProCam 1500 (not
SFI).
Here is an example of a situation to avoid. If a 225 degree feed arc is assumed in the
Feed Advisor but only 220 degrees is truly available to be fed up, punch engagement may
occur before the feed is complete and a die crash may occur. Make sure that you know
the actual number of degrees needed to feed up the material and that the feed initiate
angle is correctly set.
Here is how Feed Advisor works with the information that you provided to it. Let's say
your feed length is 2.252 inches. Also, let's say the number of degrees you have to feed in
is 225° with the feed initiate ON angle set at 260°, and the press speed is 150 SPM. You
want Feed Advisor to figure out the acceleration rate based upon these values.
How to use Feed Advisor
Select "Feed Advisor" on the "Set feed" display. Select each item on the screen, one a
time -- feed length, feed arc, and press speed -- and enter new values. For instance,
when you select "Feed length" and enter 2.252, here is how the screen will look (Figure
3-13). Remember to use your left/right and up/down CURSOR keys to set the value and
the ENTER key to enter it.

Now do the same for "Feed arc" and "Press speed". Select "Feed arc", and enter 225.
Then select "Press speed" and enter 150.
Keep in mind for variable speed presses, enter
the press speed that you will use for the job, and enter it in strokes per minute.
Once you have entered these values, here is how the "Feed Advisor" will display them:
