Parameters: %1 = Axis %2 = String: MD identifier Definitions: Machine axes which can be activa ted on several NCKs through MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB must be assigned to a master NCU in MD30554 $MA_AXCONF_ASSIGN_MASTER_NCU. For axes that are activated on only one NCU, the number of this NCU or 0 must be entered as master NCU. An assignment can only be made with MD30554 $MA_AXCONF_ASSIGN_MASTER_NCU if the machi ne axis is also addr essed via a channel MD20070 ($MC_AXCONF_MACHAX_USED+ MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB). Reaction: NC not ready. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Diagnostics Manual (DAsl), 03/2009 Remedy: Correct MD30554 $MA_AXCONF_ASSIGN_MASTER_NCU and/or MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB. Program Continuation: Switch control OFF - ON.
