248 ● VA  DMC-40x0 Command Reference 
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.
