Description
bA.02 Aux Calc
Type
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.

M: Main frequency reference (Hz or rpm)
G: Auxiliary reference gain (%)
A: Auxiliary frequency reference (Hz or rpm) or gain (%)
bA.03 Aux Ref
Gain
Adjust the size of the input (bA.01 Aux Ref Src) configured for auxiliary
frequency.
In.65–71 Px Define
Set one of the multi-function input terminals to 40(dis Aux Ref) and turn it
on to disable the auxiliary frequency reference. The inverter will operate
using the main frequency reference only.
