9.3.3 Inverter Register File Number Offset Format
The formula to calculate which register is targeted in the interface card is provided in Equation 3.
( )
offset+×= 10010 -number fileregistertarget
Equation 3
In Equation 3, “target register” ∈[1…1899], “file number” ∈[10…28] (which means N10…N28), and
“offset” is restricted only by the limitations of the programming software (but is a value of 1899 max).
Refer to section 4.1 for the register list. Table 35 provides some examples of various combinations of
file/section numbers and offsets/elements which can be used to access inverter registers. Note that
there are multiple different combinations of file/section numbers and offsets/elements that will result in
the same inverter register being accessed.
