Use the
operator to assign the captured commanded position to a variable, or to make a comparison

against another value.
Syntax: VARn=PCCc where "n" is the variable number, and "c" designates trigger A or B, or M for the
input; or PCC can be used in an expression such as IF(PCCB>2345Ø).

About Position Capture: The commanded position can be captured only by an input that is defined as a
"trigger interrupt" input with the
