Sinumerik Alarm 28020 NCU link: too many link axes configured %1

Parameters:
%1 = Number of link axis connections

Definitions:
Unfortunately, the communication capacity of the NCU link is insufficient for this link axis configuration. The link axis configuration is determined by the following MDs:
• $MN_AXCONF_LOGIC_MACHAX_TAB
• $MN_AXCT_AXCONF_ASSIGN_TAB1 … and all further container def.

Reactions:
– Alarm display.
– Interface signals are set.
– NC not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.

Remedy:
Connect a smaller number of axes across the link or combine the axes in fewer containers. Machine data to be changed: • $MN_AXCONF_LOGIC_MACHAX_TAB • $MN_AXCT_AXCONF_ASSIGN_TAB1 … and all further container def.

Program Continuation:
Switch control OFF – ON.
