Boehringer VDF 560 DUS CNC Lathe got error 2047

[Gimm3gimlet]

I'm dealing with this 1997 Boehringer VDF 560 DUS lathe with a Sinumerik 805 controller (v5.3).

I'm trying to do a simple linear cut with a radius/chamfer, but I keep getting this "Error 2047. Option not available. Check MD"
The weird part is, I know the machine can do it because there are a bunch of old programs saved on the controller that use this function.
I'm guessing a setting got changed. I've looked everywhere for the v5.3 documentation, but can only find an old v4.2 version.

Does anyone know what this error means or where I can find the right documentation?
Or maybe you guys know what to check here.

I'd really appreciate any help!

Error 2047 on an 805 usually means an MD parameter is set incorrectly. The MD parameters for radius and chamfering are usually related to MD1384 and MD1385, so check if these are set to 1 or true. Since you know the function works, a good quick fix is to copy one of the old programs that uses the feature, save it under a new name, and modify it for your new part. As for documentation, try checking CNC Manual or the Siemens Industry Support Portal. Even if they don't have the exact v5.3 manual, they often have later or earlier versions that are close enough for these basic MD parameters. I think the v4.2 manual would be enough for this kind of issue.

Error 2047 means that the controller is trying to access a feature that's currently disabled in the machine data (MD). Since older programs utilize that function, it's likely that the MD settings have been modified or reset. Check out MD5014.6, this setting controls blueprint programming and radius/chamfer options. If it's off, you'll need to turn it back on through the service menu. Also, make sure that no other MD bits related to contouring or cycle options have been disabled. If you can't find the v5.3 documentation, the v4.2 manual can still provide guidance on the basic MD structure, as it's generally consistent across versions

Appreciate you sharing that. I’m helping a friend get his old 840D back online after it sat unused for a few years, and we’re running into similar errors. Do you know if MD5014.6 applies to older builds too, or is it more of a newer control thing?
