Parameters: %1 = Channel number %2 = String: MD identifier %3 = Index: MD array index Definitions: Only axes that have been activat ed in the channel by means of MD20070 $MC_AXCONF_MACHAX_USED [kx]=m may be declar ed as geometry axes or transformation axes by means of the MD20050 $MC_AXCONF_GEOAX_ ASSIGN_TAB [gx]=k. This also applies to MD22420 $MC_FGROUP_DEFAULT_AXES (gx: Geometry axis index, kx: Channel axis index, k: Channel axis no., m: Machine axis no.). Assignment of geometry axes to channel axes MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB (includes channel axis no. k): - Geometry axis index: 0, 1st channel: 1, 2nd channel: 1 - Geometry axis index: 1, 1st channel: 2, 2nd channel: 0 - Geometry axis index: 2, 1st channel: 3, 2nd channel: 3 Diagnostics Manual (DAsl), 03/2009 MD20070 $MC_AXCONF_MACHAX_USED (includes machine axis no. m): - Channel axis index: 0, 1s t channel: 1, 2nd channel: 4 - Channel axis index: 1, 1s t channel: 2, 2nd channel: 5 - Channel axis index: 2, 1s t channel: 3, 2nd channel: 6 - Channel axis index: 3, 1s t channel: 7, 2nd channel: 0 - Channel axis index: 4, 1s t channel: 8, 2nd channel: 0 - Channel axis index: 5, 1s t channel: 0, 2nd channel: 0 - Channel axis index: 6, 1s t channel: 0, 2nd channel: 0 - Channel axis index: 7, 1s t channel: 0, 2nd channel: 0 Reaction: NC not ready. Mode group not ready, also effective for single axes NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Remedy: Please inform the authorized personnel/service department. Correct - MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB - MD24... $MC_TRAFO_AXES_IN_... - MD24... $MC_TRAFO_GEOAX_ASSIGN_TAB_... - MD22420 $MC_FGROUP_DEFAULT_AXES - and/or MD20070 $MC_AXCONF_MACHAX_USED. Program Continuation: Switch control OFF - ON.
