ES
FUNCTION: 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 command VM. When m>n, the resolution of the first axis, x, will be divided by the
ratio m/n. When m<n, the resolution of the second axis, y, will be divided by n/m. The
resolution change applies for the purpose of generating the VP and CR 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.
