Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between the analog terminals A1, A2, and A3 using multi-speed inputs.
to Multi-Step Speed Selection on page 106
Setting 2: BACnet or MEMOBUS/Modbus Communications
This setting requires entering the frequency reference via the RS-485 serial communications port (control terminals TXRX+
and TXRX-). Refer to MEMOBUS/Modbus Configuration on page 326
Setting 3: Option Card
This setting requires entering the frequency reference via an option board plugged into connector CN5 on the bypass control
board. Consult the option card manual for instructions on integrating the drive with the communication system.
