First, apologies - I know there were some old threads on this subject but I can't find them anymore...
I have a Torq Cut 22/DX32 VMC. Every few months, the thyristor (Grayhill 70M-OAC5A) which controls the "out" direction of the tool changer fails on the LC-TLAUF board. I've now replaced it three times in two years. Any ideas about the root cause of this problem so I can eliminate it?
TIA,
Mark
