Current Input
Input terminals, A1, A2, and A3 can accept a current input signal. Refer to
Table 4.16 for an example to set terminal A2 for
current input.

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. Refer
to Multi-Step Speed Selection on page 157 for details on using this function.
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-).
Setting 3: Option card
This setting requires entering the frequency reference via an option board plugged into connector CN5-A on the drive control
board. Consult the option board manual for instructions on integrating the drive with the communication system.
Note: If the frequency reference source is set for Option PCB (b1-01 = 3), but an option board is not installed, an oPE05 operation error will be
displayed on the digital operator and the drive will not run.
