This maybe the case as I remember an old Hitachi Seiki Fanuc 6M 1984 having the same problems with the tool changer. First it was a Solenoid Sticking Problem as Arr50w mentions, then it was a Mother or Main Circuit Board Issue. This drove everyone Nuts for Months. 6 Months as a matter a fact. When it was fixed it worked for about 3 more months then the Control took a dump. BYE, BYE Hitachi, Hello, Enshu VMC 650 Fanuc 11M 1986 We needed a CAT50 anyway for Titanium work.
