5.1 Operating with Auxiliary References
Frequency references can be configured with various calculated conditions that use
the main and auxiliary frequency references simultaneously. The main frequency
reference is used as the operating frequency, while auxiliary references are used to
modify and fine-tune the main reference.

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 Frq 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
– +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)].
