Sinumerik Alarm 4031 Channel %1 link axis %2 defined for more than one channel in machine data %3
%1 = Channel number
%2 = Index: Axis number for logical axis assignment
%3 = String: MD identifier
Occurs only with an NCU link system. The specified axis was defined several times or in several channels in machine data $MC_AXCONF_MACHAX_USED. If an axis is to be defined in several channels, a master channel must be assigned to the axis with the axial machine data $MA_AXCONF_ASSIGN_MASTER_CHAN. This error can only occur with an NCU link axis. The cause of a definition error can also be an NCU link communication failure. The link communication failure must be indicated separately by further alarms.
