Note
For programming positioning axes, please observe the following documentation:
Further information
See V1: Feedrates (Page 125) and S1: Spindles (Page 733)
Note
The maximum number of positioning axes that can be programmed in a block is limited to the
maximum number of available channel axes.
Definition
Positioning axes are defined using the following parameters:
● Axis type: Positioning axis type 1, type 2 or type 3
● End point coordinates (in absolute dimensions or in incremental dimensions)
● Feedrate for linear axes in [mm/min], for rotary axes in [degrees/min]
Example: Positioning axis type 1
Program code
POS[Q1]=200 FA[Q1]=1000
Example: Positioning axis type 2
Program code
POSA[Q2]=300 FA[Q2]=1500
