VR (Vector Speed Ratio)
[Motion]
DESCRIPTION:
The VR sets a ratio to be used as a multiplier of the current vector speed. The vector speed can be set by the
command
or the operators < and > used with
and
(Linear Interpolation Distance)
commands. VR takes effect immediately and will ratio all the following
vector speed commands. VR doesn't ratio acceleration or deceleration, but the change in speed is
accomplished by accelerating or decelerating at the rate specified by
ARGUMENTS: VR s,t
where
s and t are between 0 and 10 with a resolution of .0001. The value specified by s is the vector ratio to apply
to the S coordinate system and t is the value to apply to the T coordinate system.
USAGE:
OPERAND USAGE:
_VRn contains the vector speed ratio of the specified coordinate system, S or T.
RELATED COMMANDS:
EXAMPLES:
*Note UseVR for feedrate override, when specifying the speed of individual segments using the
operator ‘<’.
