I am fighting a y axis issue on a machine have sign of life alarms and i noticed that x axis is always fine but y and v are not. I also noticed that parameter 879.0 is 1 on x and 0 on both y and v. Now since this deals with profibus configuration why would you not want this the same on all axis? I checked parameters against factory settings and they match but wondered if someone configuring drives set one up wrong. Would it hurt to change this and try running the machine to see if it solves issues or atleast eliminate the machine side?
