Description
bA.02
Aux Calc Type
The table below list the available calculated conditions for the main
and auxiliary frequency references. Set the auxiliary reference gain with
bA.03 (Aux Ref Gain) to configure the auxiliary reference and set the
percentage to be reflected when calculating the main reference. Note
that items 4–7 below may result in either plus (+) or minus (-)
references (forward or reverse operation) even when unipolar analog
inputs are used.

bA.03 Aux Ref
Gain
Adjust the gain of the auxiliary reference source selected in bA.01 (Aux
Ref Src).
In.65–69 Px
Define
Set one of the multi-function (digital) input terminals to 40 (dis Aux
Ref) and activate it to disable the auxiliary frequency reference. The
inverter will operate using the main frequency reference only.
