Fanuc OM-C Fourth axis.

[pauldkeeton]

I was asked to add a fourth axis to a mill we have. I have the drive, motor and cables. I have the 4 axis card in the machine already. To bring up the 8000 series parameters for the fourth axis, do I have to bring it up in IPL mode and enter number of axis =4? Is IPL mode holding (. and -) keys at power on?

Thanks,
Paul

No IPL in OM, change PWE to a 1. Many parameters to change. Did the machine have a 4th axis on it before or is this a new add on?

You will need to enter the tuning and CMR/DMR parameters, also is the operator panel set up for it, homing switches etc? This is done in the PMC (ladder).
Do you have a parameter manual, or need one?

It didn't have the 4th axis originally.....the control does have the four axis servo board (original) and GEFanuc service said I should be able to do it. What do I have to do to get the 8400 parameters to come up? My parameters are stopping at 8399. Will the 8400's come up after I turn on another parameter? I have a parameter manual and it has all kinds of parameters for the 4th axis but the 8400 servo parameters are not coming up on screen. And yes I have the proper keypad with jog buttons etc.....
Do I have to turn on a 900 parameter for this? If so, wich one and how?

I don't see anything in the 900's that mention parameters.
Also I don't see any above 8399?
The 900 I have that are not verified are 907 #3 is Additional axis control and 915 #5 which is 5 axis control.
The PWE bit is set to 1 in MDI to change the 900 parameters.
