Function Blocks UM353-1
March 2003 3-10
3.2.2 ACS - ARCCOSINE
ACS_ function blocks, in firmware 1.30 and higher, accept an
input between -1.0 and 1.0. Each provides an output signal in
radians of which the input is the cosine.
3.2.3 ADD_ - Addition
ADD_ function blocks perform arithmetic addition on
three input signals. Any unused input will be set to 0.0
and will have no affect on the output.
All inputs should have the same engineering units. If
units are not consistent, an SCL (Scaler) function block
can be used or an alternative is to use a MATH function
block that has built-in scaling functions.
