I have bought used machine ROMI G15SM, 2001. y. (lathe with sub-spindle - B axis)
Control is GE Fanuc 18i-TA
I have problems with home referencing, zero return.
Here is scan from operation manual that i got with machine.
When I started machine for the first time, I got alarm:
300 B AXIS NEED ZRN
I have done procedure from last picture, and just B axis went to zero.
The problem is that position of zero is wrong, it is in the middle of the stroke. It should be on right edge, so all movements are in negative direction.
So, after that, machine is 100% functional, everything works!!!
And if I turn off machine and than turn on, there is no alarm and I can not make home reference return. But machine is fully functional.
I have found some manuals in PDF for same machine but for "V 2.0 line".
Please check next picture.
Obviously, this should be for my machine, but I am not sure.
And now I am very confused, does it have absolute encoders or not?
There are no LED-s that indicates zero point accheved (like there is on my two VMC-s)
And I can not found any limit switches, neither physically on machine nor in electric diagram.
SECOND PROBLEM, but I think related to first.
Look at the next picture. Offsets wear/geometry are all cleared and work coordinate systems all set to 0.
I think that dimensions RELATIVE / ABSOLUTE / MACHINE should be exactly the same for each axis (is all compensations are off, and I think they are).
You can see that Z and C have some differences......
