VS
FUNCTION: Vector Speed
DESCRIPTION:
The VS command specifies the speed of the vector in a coordinated motion sequence in either the
LM or VM modes. VS may be changed during motion.
Vector Speed can be calculated by taking the square root of the sum of the squared values of speed
for each axis specified for vector or linear interpolated motion.
ARGUMENTS: VS s,t where
s and t are unsigned even numbers in the range 2 to 22,000,000 for servo motors and 2 to
6,000,000 for stepper motors. s is the speed to apply to the S coordinate system and t is the
speed to apply to the T coordinate system. The units are counts per second.
s = ? Returns the value of the vector speed for the S coordinate plane.
t = ? Returns the value of the vector speed for the T coordinate plane.
