Dear All,

We have a yang smv-1000 with fanuc 0-md controller My questions as below

We tried change 900 option parameter for the 4th axis but all parameter change back to 0 again, why we can not change some option parameter?

Yang SMV-1000 does not has 4 axis select button, after install 4 axis how can make zero point 4th axis, what kind of button we need or what? Or we will use direclty G28 A0.?

We have another breand with Fanuc 0-M series taiwan cnc machine, we change 907.3 to 1 and D493.7 we shut down and open again this machine 4 axis is valid, about yang which diagnostic we need the change?

Thanks&Rgeards
