Trigger point for erosion depth
The trigger point for the erosion depth switches the EDM
generator off. The electrode automatically moves up to the
start position.
End of the EDM process
As soon as the start position (HOME) has been reached or
crossed over in the positive direction, the transistor for the
start position is locked (depends on P21). All transistors,
except A5, are then locked and the initial condition is
restored. At this stage, a new EDM process can be started.
Example of input for switching outputs
Switching output:
Input:
Start position (HOME) + 10.000 mm
1st trigger point before MIN position 3.000 mm
2nd trigger point before
MIN position (P17 or P18) 0.100 mm
1st trigger point before reaching
the erosion depth 2.000 mm
2nd trigger point before reaching
the erosion depth 1.000 mm
Trigger point for erosion depth (END) - 20.000 mm
