VA
FUNCTION: Vector Acceleration
DESCRIPTION:
The VA 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 67107840. 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.
