The situation is this:
I have created a main program. In that program I call 2 different programs for different working areas (left and right).
In those programs, there are sub -programs, makros and etc.
While running the Main program in Manual T1/T2 (step mode) sometimes about 30 cycles or less, during running some subprograms, they skip out of Main program and it completely abort the Main, so the robot stays in the subprogram. When that happens it shows Error INTP-105 and MCTL-003 errors, but after i checked them in the Fanuc Alarm PDF - they don't say much. Only reset errors and continue. The only way to continue is after reset, to abort the subroutine and manually choose Main program, get back on the same place in the program and it continues like nothing happened without any errors.
It looks like a buffer or Memory which cannot hold so many processes and needs to be reset. But this is not good for Automatic mode, obviously.
Please, if you have knowledge of this, let me know.
