Rotary axis speed way too slow Siemens 840D

Tried to program a simple polar pocket with three repeats on my DMG DMU103V and the program runs, (after my post guy made some changes to put an X -Y axis move on the same line as all the A axis moves and fix repeats), but the A axis moves are at the F speed of 16, in degrees per minute! Waaaay to slow. My post guy suggested that I replace G70 in line N6 with G700 but my control is too old to recognize it.


This 4th was never used by the previous owner after initial install by DMG at purchase. I think there's some parameter that needs to be changed but rather than read through 5 or 10,000 pages of Siemens manuals or waste a few days getting no answers from DMG tech support, I thought Id ask here first.

Try setting the rotary axis reference radius with FGREF.

FGREF[A] = radius

What cadcam are you using? Can you use Inverse Time feed?

Click to expand...

I guess my control is too old for that command, it stops at the FGREF line

My post guy send a modified post over today and it now outputs correctly. Heres the output for the same part (.2" DOC instead of .1") that works fine.
