DMC-40x0 Command Reference VD • 249
VD
FUNCTION: Vector Deceleration
DESCRIPTION:
This command sets the deceleration rate of the vector in a coordinated motion sequence.
ARGUMENTS: VD s,t where
s and t are unsigned integers in the range 1024 to 1073740800. s represents the vector
deceleration 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 deceleration for the S coordinate plane.
t = ? Returns the value of the vector deceleration for the T coordinate plane.
