Description of Switching Output Functions
(Settings in parameter P21: “STANDARD”)
After an EDM process, the transistors A1, A2, A3, A4 and A6
are locked. A5 is conductive.

A1, A2, A5, A6 switch whenever the the trigger point is
traversed.
A3, A4 switch only once, i.e. when the trigger point is
traversed for the first time.
Start position (HOME) referenced to display value 0,
programmable with the keys.
Trigger points before MIN position
1st trigger point before MIN position, programmable with
the keys.
2nd trigger point before MIN position, programmable in
parameter 17 which is protected by a code number.
Trigger points with respect to erosion depth
1st trigger point before reaching the erosion depth,
programmable with the keys.
2nd trigger point before reaching the erosion depth,
programmable with the keys.
Trigger point for erosion depth, programmable with the
keys.
