General

Note
For the programming of position axes, please observe the following documentation:
References:
Programming Manual Basics; Section: "feed rate control" and "spindle motion"
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

Meaning
The following is effective as maximum axial jerk for positioning axis motions:
0 MD32430 $MA_JOG_AND_POS_MAX_JERK
With active G75 (fixed-point approach): MD32431 $MA_MAX_AX_JERK[0]
1 MD32431 $MA_MAX_AX_JERK[1]
Comment
; Axis Q1 with feedrate 1000mm/min at Position 200.
Comment
; Axis Q2 with feedrate 1,500mm/min at Position 300.
