I have an 828 control on a 5 axis. Does anyone know how to precall a tool so that if the operator pushes cycle stop while the magazine is indexing it wont alarm out and need the mag referenced. All the fanucs dont have this problem. you can press feed hold while the tool that is precalled is coming around and it stops machine motion but not the magazine. It stops when it arrives at the precalled tool. Is there a production mode or something i am not aware of?

This procedure is made by the PLC !!! If the creator don´t think about that and don´t write in the plc program, you will have this problem all life !!!!!

If it is an 828D then you don't have a full 5 axis machine that supports simutaneous 5 axis machining. You would be able to do 3+2 5 axis control. The previous post is fairly accurate in that this function is likely how the builder designed the PLC logic. Who is the machine tool builder? Model #?
