Hi everybody,
I'm getting Alarm 4400 [4] - NOT READY (ARITH), always on the same job and line number.. gets stuck on a MOVJ like forever while testing with INTERLOCK+TEST START, if I release the buttons and try again it rings the alarm.. resetting it and running once more makes the robot continue..
In some cases it gets stuck on an IF statement which should be already evaluated, releasing the buttons and pressing again makes it go on with the other instructions; this IF statement is into a job called by the previous, which opens and closes the gripper and verifies the sensors.
Moreover, on the same job it may also "wait" on a different MOVJ which was not completed, it just stops few millimeters below, and trying to restart with INTERLOCK+TEST START many times doesn't help; instead, using FWD completes the motion instruction, and eventually it would stop and fire the same 4400 alarm on the same MOVJ as mentioned in the first lines of this post.
Any idea on what could it be?
