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 VS or the operators < and > used with CR, VP and LI 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 VA and VD.
ARGUMENTS: VR n where
n is an integer with a resolution of .0001.
USAGE:
OPERAND USAGE:
_VR contains the vector speed ratio.
RELATED COMMANDS:
EXAMPLES:
NOTE: UseVR for feedrate override, when specifying the speed of individual segments using the
operator ‘<’.
