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 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)’].
