Machine: Kitamura Mycenter 2 VMC (umbrella style tool changer)
Control : Fanuc 6MB
Problem:
Occasionally, the control will reset the current tool to #1 at program start.
Usually happens on first run after power-up but will occasionally occur after several hours of running (but always at prog. start).
I can reset to the correct number via the parameter page.
Obviously this is only noticed when running a prog. that starts with something other than T1.
I have been running the same program for the past 2 weeks. It has an air blast in it that does throw chips into the tool carousel.
Just reading my diagrams, I don't see any type of carousel position feedback, might there be something in the servomotor that I should look at?
Any boards I should investigate?
Thanks,
Bob
