OK. Clear the error. Is it all better now?

Seriously, you started 2 threads, and the sum total of info you gave is you've got an AB Ultra 3000 Servo Drive, and fault #19.
Are the cables properly connected?
Does the enocder work?
Is the drive train operating properly?
Do you have the proper motor selected?

1919: Following Error

Description: ON indicates the Following Error Limit, set above, has been exceeded.

Possible Causes: Position error limit exceeded.

Suggested Action:

Retune the drive, start by setting the feedforward gain to 100%.
Increase the Following Error Limit and Time.
If in Follower Mode, increase the Slew Limit (in the Follower window).
Check position loop tuning.

From Ultraware v1.63s's Help section.

Hello CroCop
- The Cable are O.K.
- The Encoder check Ok with good drive ( Swapped )
- Drive Train O.K. Manually and drive good with swapped drive
- Motor configuration are O.K.
Thank you for your help

Wally,

You need to describe your original problem and why you have done what you have done. IT seems that changing the drive and swapping things around isn't helping. My experience is this, most maintenance guys will do what you have done without checking the mechanical side of things. IF this was a working system and has been in operation for a while, then more than likely you have a mechanical problem you are overlooking.

Are you using a series c feedback cable? I had alot of problems with the B series and got a PSA from rockwell stating a problem with the cables.

Hello David,

The machine was running fine and just decided to quit due to the cold weather, I swapped to other motor to check for mechanical problem , It ran fine with other good drive, the fault 19 and fault 24 could be some parameter need to change on the Velocity setup and do you know how to manual or auto tune this drive.
Thank you for your help

WallyPrestone · January 17th, 2006, 12:50 PM

Thank you , I am going to check the cable

olias · January 18th, 2006, 10:39 AM

So Wally, How'd you make out?

WallyPrestone · January 20th, 2006, 10:55 AM

Replaced the Ultra 3000 drive , system back up O.K.
Thanks for the help

I am sorta thinking you have overlooked something. You are obviously involved in a maintenance downtime situation. I would be curious what Rockwell finds when you send it in.
