Sinumerik Alarm 16800 Channel %1 block %2 traverse instruction DC/CDC for axis %3 not allowed
Parameters:
%1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions:
The keyword DC (Direct Coordinate) can only be used for rotary axes. This causes approach of the programmed absolute position along the shortest path. Example: N100 C=DC(315)
Reactions:
– Alarm display.
– Interface signals are set.
– Correction block is reorganized.
Remedy:
Please inform the authorized personnel/service department. Replace the keyword DC in the displayed NC block by specifying AC (Absolute Coordinate). If the alarm display is the result of an error in the axis definition, the axis can be declared as a rotary axis by means of the axis-specific MD 30300 IS_ROT_AX. Corresponding machine data: Modify MD 30310: ROT_IS_MODULO Modify MD 30320: DISPLAY_IS_MODULO
Program Continuation:
Clear alarm with NC START or RESET key and continue the program.
