Bit 6
Blueprint programming
This function can simplify NC programming. You can enter the words to describe
lines and circles directly from the part drawing. See Programming Guide.
Bit 5
Cycles:
This bit activates the reference conditioning (software module), which is
essential for processing stock removal cycle L95.
Bit 3
Extended contour definition programming
This function can simplify NC programming. You can enter the words to describe
lines and circles directly from the drawing into the control. See Programming Guide.
Bit 0
The spindle encoder is taken as a basic measurement for pitch.
