Hello
Siemens Sinumerik 840, Siemens System 850M
I have the following problem (expressed in an unprofessional way):
G1 (programmable feed) doesn’t work, even thought the feed potentiometer is turned up.
It only moves for a short period of time, piece by piece.

Hope somebody can help me out...
Regards

Addition:
When we program G1 on 50 then it works without problems, but that’s not a permanent solution

Looks like a must-value/ just value conflict with a high feed, what should I do??
