4001 Channel %1 axis %2 defined for more than one channel via machine data %3
Parameters: %1 = Channel number
%2 = Index: Machine axis number
%3 = String: MD identifier
Definitions: In the channel-specific MD: 20070 AXCONF_MACHAX_USED [CHn, AXm]=x (n ... chan-
nel 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).
Reactions: - Alarm display.
- Interface signals are set.
- NC not ready.
- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- NC Stop on alarm.
Remedy: 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.
Program Continuation: Switch control OFF - ON.
4002 Channel %1 machine data %2[%3] assigns an axis not defined in channel
Parameters: %1 = Channel number
%2 = String: MD identifier
%3 = Index: MD array index
Definitions: Only axes that have been activated in the channel by means of the channel-specific
machine data 20070 AXCONF_MACHAX_USED [kx]=m may be declared as geometry
axes or transformation axes by means of the MD 20050
AXCONF_GEOAX_ASSIGN_TAB [gx]=k. This also applies to
$MC_FGROUP_DEFAULT_AXES (gx: Geometry axis index, kx: Channel axis index, k:
Channel axis no., m: Machine axis no.).
