ES (Ellipse Scale)
DESCRIPTION:
The ES command divides the resolution of one of the axes in a vector mode (VM). This function allows for
the generation of circular motion when encoder resolutions differ. It also allows for the generation of an
ellipse instead of a circle.
The command has two parameters, m and n. The arguments, m and n, apply to the axes designated by the
VM (Coordinated Motion Mode) command. When m>n, the resolution of the first axis, x, will be divided by
the ratio m/n. When mapplies for the purpose of generating the
VP (Vector Position) and CR (Circle) commands, effectively
changing the axis with the higher resolution to match the coarser resolution.
The ES command will apply to the selected coordinate system, S or T. To select the coordinate system, use
the command CAS or CAT.
ARGUMENTS: ES m,n where
m and n are positive integers in the range between 1 and 65,535.
