Fagor 800T Following Error

[MotoDan]

Hello all,

My 800T is reporting a "following error" on Z whenever the feedrate gets above a certain point. This happens whether I'm using the handwheel or during a program cycle. I have all of the manuals for both the control and the servo drives. I've looked at the servo parameter setup section in the Fagor manual as well as the section in the drive manual. My question is which should I try first - turning the pots on the drive or changing parameters on the control? Either way, it looks like the best thing to do is write a quick program to move Z back and forth in a loop while watching the following error on the control display.

Any tips would be appreciated.

That is a good idea. That's what Fagor provides with their turnkey packages for users to tune their drives.

What kind of drives do you have? Your best bet would be to make that program and tune your signal gain and also check the balance. Should be as close to o as possible when you hit cycle stop and are viewing the following error.
