Probable Faulty Locations
1)By LB35II-MATC-Y LU45-MATC-Y, a next tool preparation state is ATC operation sequence number 12 and 49. By LB15IIMATC-Y, a next tool preparation state is ATC operation sequence number 8 and 51. They are going along M06 instructions that ATC operation sequence number is not a next tool preparation state.
2)By LB35II-MATC-Y LU45-MATC-Y, a tool return operation start state is ATC operation sequence number 27 and 68.
3)M06 was issued though the turret is not indexed at the tool change position.
5)For LB15II/LB35II-MATC-Y and LU45-MATC-Y, MG commands can be issued with the ATC operation sequence number 1, 2, 41, and 42. An MG was issued with a sequence number other than 1, 2, 41,or 42.
