Switching between Main/Auxiliary Frequency References
The frequency reference input can be switched between the analog terminals A1 and A2 using multi-speed inputs.
Multi-Step Speed Selection on page 55
Setting 2: Serial Communication (APOGEE FLN, BACnet, MEMOBUS/Modbus, Metasys N2)
This setting requires entering the frequency reference via the RS-422/RS-485 serial communications port (control terminals
R+, R-, S+, and S-).
