DMC-1400 Series Command Reference VR ● 215
VR FUNCTION: Vector Speed Ratio
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 between 0 and 10 with a resolution of .0001.
n = ? Returns the value of the vector speed ratio for the coordinate plane.

using the operator ‘<’ and '>'.
