AV
FUNCTION: After Vector Distance
DESCRIPTION:
The AV command is a trippoint, which is used to hold up execution of the next command
during coordinated moves such as VP,CR or LI. This trippoint occurs when the path
distance of a sequence reaches the specified value. The distance is measured from the
start of a coordinated move sequence or from the last AV command. The units of the
command are quadrature counts.
ARGUMENTS: AV s,t where
s and t are unsigned integers in the range 0 to 2147483647 decimal. 's' represents the vector
distance to be executed in the S coordinate system and 't' represents the vector distance to
be executed in the T coordinate system.

OPERAND USAGE:
_AVS contains the vector distance from the start of the sequence in the S coordinate system
and _AVT contains the vector distance from the start of the sequence in the T coordinate
system.

Hint: Vector Distance is calculated as the square root of the sum of the squared distance for each axis
in the linear or vector mode.
