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.
Calculating final command frequency
Main reference+(bA.03xbA.01xIn.01)
Main referencex(bA.03xbA.01)
Main reference/(bA.03xbA.01)
Main reference+{Main
referencex(bA.03xbA.01)}
Main reference+bA.03x2x(bA.01–50)xIn.01
Main referencex{bA.03x2x(bA.01–50)}
Main reference/{bA.03x2x(bA.01–50)}
Main reference+Main
referencexbA.03x2x(bA.01–50)
M: Main frequency reference (Hz or rpm)
G: Auxiliary reference gain (%)
A: Auxiliary frequency reference (Hz or rpm) or gain (%)
Adjust the size of the input (bA.01 Aux Ref Src) configured for auxiliary
frequency.
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.
