Sinumerik Alarm 4001 Channel %1 axis %2 defined for more than one channel via machine data %3
%1 = Channel number
%2 = Index: Machine axis number
%3 = String: MD identifier
In the channel-specific MD: 20070 AXCONF_MACHAX_USED [CHn, AXm]=x (n … channel number, m … channel axis number, x … machine axis number), several channels were assigned to a machine axis without having a master channel defined for this axis.
There is usually not much point in assigning a machine axis to several channels.In exceptional cases, multiple assignment can be performed if a master channel is defined for this axis. The channel assignment can be performed in accordance with the machining requirements in the NC part program by means of a keyword (yet to be defined in later product versions).

Please inform the authorized personnel/service department. In the axis-specific MD 30550 AXCONF_ASSIGN_MASTER_CHAN [AXm]=n (m … machine axis number, n … channel number), a master axis was set for the axes that are supposed to be alternately assigned by the NC program to one or the other channel.
