ORIMKS constitutes the basic setting
The basic setting can be changed via the following machine data:
MD20150 MC_GCODE_RESET_VALUES (RESET position of G groups)
MD20150 $MC_GCODE_RESET_VALUES [24] = 1 ⇒ ORIWKS is basic setting
MD20150 $MC_GCODE_RESET_VALUES [24] = 2 ⇒ ORIWKS is basic setting
Illegal tool orientation
If tool position is programmed in relation to the following functions, alarm 12130 "Illegal tool
orientation" is output when Euler angles and direction vectors are selected and the NC program
then stops (this alarm can also occur in connection with G331, G332 and G63).
● G04: Dwell time
● G33: Thread cutting with constant lead
● G74: Approaching a reference point
● G75: Approaching a fixed point
● REPOSL: Repositioning to the contour
● REPOSQ: Repositioning to the contour
● REPOSH: Repositioning to the contour
To remedy this situation, tool orientation can be programmed with axis end values.
