Reading the current NC information
Use the following syntax to read NC information that was
programmed with G functions.
#wn(AW) 0: No driven tool
1: Driven tool
#wn(MD) Direction of rotation:
3: M3
4: M4
Identification codes for tool information
Access to current NC information
Syntax: #nx(select)
x = G function number
select = designates the information
to be read
Status of TRC
#n40(G) TRC/MCRC status:
40: G40 active
41: G41 active
42: G42 active
Active wear compensation
#n148(O) Active wear compensation (G148):
0: DX, DZ
1: DS, DZ
2: DX, DS
Active working plane
#n18(G) Active working plane:
17: XY plane (front or rear)
18: XZ plane (turning)
19: YZ plane (side view / surface)
