Fire mode operation
Operates the inverter in a way to cope with emergency situations,
such as fire, by controlling the operation of ventilation (intake and
exhaust) fans.

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)’].
