hello dear friends
i am new in cnc .maybe my question very simple for you, i apologize for this.
my machine before go to refrence work in auto mode so it is dangerous.
i want to chang this.
i read the parameter manual and change parameter 74 but not ok.please help me my friends .

my other question is:
parameter 8023 and 8024 for numerator and denumerator .but in my machine is zero.
why is reason , i am very confused please help me.

For the automatic zero return, this is made by your pmc, not by fanuc, so look your ladder , may be you have a keep relay to cancel that
for your parameter, i think your machine use the flexible gear and at this time, parameters 8023 24 are not used

yes i think your answer is true .but i have not any manual for keep relay in for machine
which signal , i must search in pmc ladder for reference .
and for flexible gear what is difference between use flexible gear in machine with use numerator ??
