Probable Faulty Locations
1)Faulty EC input signals for sensor head position
confirmation:I/O check NO.26 INPUT bit E (iSHRTC)–retract end
I/O check NO.26 INPUT bit F (iSHADC)–advance end
2)Programming error
Program Example:

G13
M117
:
M03 M41 S100
:
M118
:

Measures to Take
Correct the program so that the sensor head returns to the standby position before designation of the spindle rotation command.
