Sinumerik Alarm 75015 Channel %1 block %2 CLC(0) with active TOC
%1 = Channel number
%2 = Block number
The 3D clearance control has been switched off with CLC(0) while tool radius compensation is still active (G41/G42). Since CLC(0) empties the internal block buffer and transfers the current position offset of the clearance control as a “contour jump” to the interpreter, TRC must be deactivated when this command is issued.
– Alarm display.
Modify part program: Switch off active G41/G42 before CLC(0) or do not switch of clearance control, but just “freeze” temporarily (CLC_GAIN=0.0) or cancel the position offset mechanically with CLC(-1).
Clear alarm with the RESET key. Restart part program
