!WARNING Beware that giving several ADDAX commands in a system can create a dangerous
loop when for instance one axis is linked to another and vice versa. This may cause
instability in the system.

/i
Example An X-Y marking machine must mark boxes as they move along a con-
veyor. Using CONNECT enables the X marking axis to follow the con-
veyor. A virtual axis is used to program the marking absolute positions;
this is then superimposed onto the X axis using ADDAX.
ATYPE AXIS(3)=0 'set axis 3 as virtual axis
SERVO AXIS(3)=ON
DEFPOS(0) AXIS(3)
ADDAX (3)AXIS(0) 'connect axis 3 requirement to axis 0
WHILE IN(2)=ON
REGIST(3) 'registration input detects a box on the conveyor
WAIT UNTIL MARK OR IN(2)=OFF
IF MARK THEN
CONNECT(1,2) AXIS(0)'connect axis 0 to the moving belt
BASE(3,1) 'set the drawing motion to axis 3 and 1
'Draw the M
MOVEABS(1200,0)'move A > B

Type Axis parameter (read-only)
Syntax ADDAX_AXIS

which the base axis is currently linked to by ADDAX . If the base axis in
not linked to any other axis, the ADDAX_AXIS parameter returns -1.
