VA
FUNCTION: Vector Acceleration
DESCRIPTION:
This command sets the acceleration rate of the vector in a coordinated motion sequence.
ARGUMENTS: VA s,t
where
s and t are unsigned integers in the range 1024 to 1073740800. s represents the vector acceleration
for the S coordinate system and t represents the vector acceleration for the T coordinate
system. The parameter input will be rounded down to the nearest factor of 1024. The units of
the parameter is counts per second squared.
s = ?
Returns the value of the vector acceleration for the S coordinate plane.
t = ?
Returns the value of the vector acceleration for the T coordinate plane.
