Feedrate Control and Spindle Motion
7.2 Traversing positioning axes (POS, POSA, POSP, FA, WAITP, WAITMC)
Fundamentals

Example of traveling with POSA[…]=
On accessing status data of the machine ($A...), the control generates an internal
preprocessing stop, processing is halted until all previously prepared and stored blocks have
been executed in full.
N40 POSA[X]=100
N50 IF $AA_IM[X]==R100 GOTOF LABEL1 ;Access to machine status data
N60 G0 Y100
N70 WAITP(X)

Example of waiting for end of travel with WAITP(...)
Pallet feed equipment
Axis U: Pallet store, transporting the pallet to the working area
Axis V: Transfer line to a measuring station, where sampling controls are carried out:
N10 FA[U]=100 FA[V]=100 ;Axis-specific feedrate functions for
;each positioning axis U and V
N20 POSA[V]=90 POSA[U]=100 G0 X50 Y70 ;Traverse positioning and path axes
N50 WAITP(U) ;Execution of the program is only
;continued when axis U has reached the
;end position programmed in N20.
N60 …
Traveling with POSA[…]=
The axis indicated in square brackets is traversed to the end position. The block step enable
or program execution is not affected by POSA. The movement to the end position can be
performed during execution of subsequent NC blocks.
