Not sure what has happened to my machine, but after cycling the ATC to clean it up it landed on "standby" tool 5 and threw up that alarm. We are unable to clear the alarm and it has locked up the machine from doing anything.
We have taken the covers off to inquire with the ATC to see what is going on, but we are not sure what to do to clear this alarm.
Not to sound dumb, but did you look for a mag sensor/s to see if it/they have chips or anything on it? Are you cleaning with compressed air? That would be a likely culprit. Or else test it some how? It must use that sensor to Keep track of the positions of the tool changer. There are probably several different ones in there. Do you have any documentation of the wiring or ladder for the machine? What do you mean by "standby" tool? Is there a tool currently in the spindle?
