Siemens alarm 14900: Channel %1 block %2 center point and end point programmed simultaneously
SINUMERIK channel alarm · Siemens 840D/810D powerline
What it means
The circle block contains contradictory geometric descriptions: both a center-point specification and a mutually exclusive end-point/radius description were given in the same block. Only one circle definition method may be used per block. Remove the redundant data and keep I/J/K or CR=/AR= consistently.
Likely causes
- Postprocessor emitting both center and radius words
- Hand edit adding I/J/K to an existing CR= block
- Template mixing two circle programming styles
