Requirement: The Z axis must be known in the 1st and 2nd channels
1. Program sequence in the first channel:
Program code
WHEN TRUE DO RELEASE(Z)
; Read-in disable as long as Z axis is program axis
WHENEVER $AA_TYP[Z] == 1 DO RDISABLE
N110 G4 F0.1
...
; Z axis returns to status as NC program axis
WHEN TRUE DO GET(Z)
; Read-in disable until Z axis is program axis
WHENEVER($AA_TYP[Z]<>1) DO RDISABLE
N120 G4 F0.1
...
WHEN TRUE DO RELEASE(Z)
; Read-in disable as long as Z axis is program axis
WHENEVER $AA_TYP[Z] == 1 DO RDISABLE
