Settin 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-).
Refer to MEMOBUS/Modbus Configuration on page 340
Settin Option Card
This setting requires entering the frequency reference via an option board plugged into connector CN5 on the drive control
board. Consult the option card manual for instructions on integrating the drive with the communication system.
If the frequency reference source is set for Option PCB (b1-01 = 3), but an option board is not installed, an oPE05 Programming Error will

This setting requires entering the Run command via the digital input terminals using one of following sequences:
• 2-Wire sequence 1:
Two inputs (FWD/Stop-REV/Stop). Set A1-03 to 2220 to initialize the drive and preset terminals S1 and S2 to these
functions. This is the default setting of the drive.
