Can anyone advise how to determine the appropriate parameter settings for a 4th axis on a Fanuc 0m-C? The machine formerly had a 4th axis, but I don't have that unit and don't know what reduction it had.
What I am trying to do is set up the machine to use my Tsudakoma 4th axis and my 5c indexer depending on the work I am doing. They both have 5 series motors with 2000 PPR encoders. I have them both working and wired identical, but they have different gear reduction ratios, so I need to figure the parameter settings for each. One has a 120/1 reduction and the other a 180/1.
I have the 68335 Maintenance Manual and have found the list of parameters related to the 4th axis, but can't seem to sort out the ratio aspect. All else it good.
Regards,
John
