Program Continuation:

Channel %1 block %2 illegal tool orientation

%1 = Channel number %2 = Block number, label

The tool orientation may only be contained in a modal motion block or in a WAB block (repositioning).

It can be programmed via Euler angles (A1, B1, C1), normal vector components (A2, B2, C2), direction vectors (A3, B3, C3) or the axis end values. If the tool orientation is programmed in conjunction with the functions:

G04 (dwell time), G33 (thread cutting with constant lead), G74 (approach reference

points) or REPOSL, REPOSQ, REPOSH (repositioning)

then an alarm is issued with Euler angles, direction vectors and normal vector


-    Correction block

-    Interface signals are set.

-    Alarm display.

Press the NC Stop key and select the function "Correction block" with the softkey PROGRAM CORRECT. The correction pointer positions on the incorrect block.

Program tool orientation with the axis end values or use a separate block for this.

Clear alarm with NC START or RESET key and continue the program.
