Siemens alarm 12060: Channel %1 block %2 same G group programmed repeatedly
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
Two or more different G codes from the same modal group appear in one block, e.g. G0 together with G1. Only one member of each G group may be active per block. Remove the redundant code - usually a postprocessor artifact or hand-editing mistake.
Likely causes
- Postprocessor emitting duplicate group codes (e.g. G17 G18)
- Hand-edited block merging two motion commands
- ISO dialect conversion errors
