I have a robo drill fanuc control 16iB with a kawatate c pallet changer. Were running a simple 2 hole drill program with a oallet swap. At the very end of the program it takes pallet a into the APC then just sits there hung up on

N400 m63 ;

It got there apparently because neither 1004 or 1005 variable EQ 1. Ihave no idea what these variables are other than inputs. Anyone have any experience with this?
