electronica EL400 Manual

Congratulations on the purchase of your Electronica 400 series mill kit. This article addresses how to
program and recall SDM (Sub Datum Memory) points.
You must first program points into the SDM function before you can recall points. The SDM function has
two programming modes – Program "ProGrAM" and Learn "LEArn".
The first programming mode, "ProGrAM", requires the user to enter the point error distance in a list like
format. Although this mode doesn't require the operator to proceed to each individual point, it does
require the user to enter not the coordinate value, but rather the error distance of each point from ABS
zero, which vastly complicates programming.
The "LEArn" mode requires the user to proceed to each point individually, and then "captures" each point
as the mill moves from point to point. Although somewhat slower, the "LEArn" mode is intuitively easier,
as the user can "see" each waypoint as it is entered. For this reason, DRO PROS recommends our
customers use the "LEArn" mode when programming SDM points.
Before starting to program SDM points, the user should first set a meaningful ABS zero point on your
part. This may be on the centerpoint, bottom right corner, an easily indexable point, etc. Remember, all
your SDM points index off of your ABS zero point, so it should be set to something that's easily
repeatable on multiple parts.
Programming SDM points via Learn Mode (easier, more intuitive):
1. To enter the SDM mode,
The x axis display window should now read "ProGrAM", and "abs" and "fn" and should be lit in red along
the lower edge of the display.
2. Push the "6" key once. The x axis display window should now read "rUn".
3. Push the "6" key once. The x axis display window should now read "LEArn".
4. Push the "ent" key
display window.
5. Push the "Y" axis key once, then enter the SDM point you want to start programming from (in
this example 1), followed by the "ent" button.
X, Y and Z coordinate values displayed on the front.
6. Move your mill to the first point you want to program into SDM memory. The display values in the X, Y
and Z axis will change as you move the mill.
7. Push the "6" key
start point you programmed in step #5). This confirms which SDM point you are programming.
8. Push the "6" key
The display will now return to the SDM abs window, with X, Y and Z coordinate values displayed on the
front.
