The table above lists the available calculated conditions for the main and auxiliary
frequency references. Refer to the table to see how the calculations apply to an example
where the DRV-06 Frq Src code has been set to ‗0 (Keypad-1)‘, and the inverter is
operating at a main reference frequency of 30.00 Hz. Signals at -10 to +10 V are received
at terminal V1, with the reference gain set at 5%. In this example, the resulting frequency
reference is fine-tuned within the range of 27.00–33.00 Hz [Codes IN-01–16 must be set to
the default values, and IN-06 (V1 Polarity), set to ‗1 (Bipolar)‘].

None
Auxiliary frequency reference is disabled
1
V1
Sets the V1 (voltage) terminal at the control terminal
block as the source of auxiliary frequency reference.
3
V2
Sets the I2 (voltage) terminal at the control terminal block
as the source of auxiliary frequency reference (SW4
must be set to ‗voltage‘).
4
I2
Sets the I2 (current) terminal at the control terminal block
as the source of auxiliary frequency reference (SW4
must be set to ‗current‘).
5
Pulse
Sets the TI (pulse) terminal at the control terminal block
as the source of auxiliary frequency reference.
BAS-02
Aux Calc Type
Set the auxiliary reference gain with BAS-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.
