Sinumerik Alarm 14120 Channel %1 block %2 plane determination for programmed orientation not possible
%1 = Channel number
%2 = Block number, label
The programmed orientation vectors (direction vectors) in the beginning of block and end of block point include an angle of 180 degrees. Therefore the interpolation plane cannot be determined. Example:
N50 TRAORI (1)
N55 A3=0 B3=0 C3=1
N60 A3=0 B3=0 C3=-1 ; the vector of this block is precisely opposite to that in the preceding block.
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.
Modify the part program so that the orientation vectors of a block are not directly opposed to each other, for instance by dividing the block up into 2 sub blocks.
Clear alarm with NC START or RESET key and continue the program.
