Sinumerik Alarm 4031 Channel %1 link axis %2 defined for more than one channel in machine data %3
Parameters:
%1 = Channel number
%2 = Index: Axis number for logical axis assignment
%3 = String: MD identifier
Definitions:
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.
Reactions:
– Alarm display.
– Interface signals are set.
– NC not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
Remedy:
Correct the machine data $MC_AXCONF_MACHAX_USED or assign a master channel.In the event of a link communication failure, these error causes have to be remedied first.
Program Continuation:
Switch control OFF – ON.
