CRAT(?) [ X | Y | R | j ] { , OFF | ON | i }
The
CRAT j, i
(i=0) or on (i=1). Setting an ratio for phase is not allowed.
The ratio function for X and Y are tied to aux input voltage 3, following the equation
The ratio function for R is similar, but is tied to aux input voltage 4:
Example
CRAT X, ON
CRAT 0, 1
CRAT? 0
CRAT? X
command turns the ratio function for X (j=0), Y (j=1), or R (j=2) to off
