Code
1->The spindle rotation command (M03, M04) is issued.
2->M-tool rotation command (M13,M14) is issued.
3->Axis movement command is issued.
4->Turret index command is issued.
5->Chuck open/close command is issued.
6->Steadyrest open/close command is issued.
7->The tool breakage sensor was not retract position during spindle rotation.
8->The tool breakage sensor was not retract position during M-spindle rotation.
9->The tool breakage sensor was not retract position during axis movement or C-axis movement.
10->The tool breakage sensor was not retract position during turret indexing.
11->The tool breakage sensor was not retract position during door is not close.
12->The tool breakage sensor was not retract position during coolant supply.
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.
