I have a Mori Seiki SL2H with a Fanuc 3t controller, my question is why when in a program m42 is high gear which is correct.But if you put a larger part in and need to run in low gear M43 it will not run the porgram. The spindle will not start in auto . It works fine running it manuel in high or low , is it just a parameter setting i even tryed to fool it by letting it pickup the off set in m42 and get in position then giving it a m43 dont work
 
I did the M41 I just said M43 I was mistaken. it will not run in low gear in AUT. run fine in low if you run it manual
 
Check the limit switch that confirms the completion of shifting into low. Best is to find the input address into the control and check status there. That confirms switch and wiring is ok or not.
thank you so much, every time i have had to ask a question you know the answer thats going to take me a while to complete that, you know these machines, Thanks again
