Figure 1.2 Setting the Frequency Reference as a Current Signal to Terminal A2
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 52
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-).
Refer to MEMOBUS/Modbus Configuration on page 280
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.

Setting 1: Control Circuit Terminal
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.

• 3-Wire sequence:
Three inputs (Start-Stop-FWD/REV). Set A1-03 to 3330 to initialize the drive and preset terminals S1, S2, and S5 to these
functions.
Refer to Setting 0: 3-Wire Sequence on page
Setting 2: Serial Communication (APOGEE FLN, BACnet, MEMOBUS/Modbus, Metasys N2)
This setting requires entering the Run command via serial communications by connecting the RS-422/RS-485 serial
communication cable to control terminals R+, R-, S+, and S- on the terminal block.
Configuration on page 280
Setting 3: Option Card
This setting requires entering the Run command via the communication option board by plugging a communication option
board into the CN5 port on the control PCB. Refer to the option card manual for instructions on integrating the drive into the
communication system.
Note:
If b1-02 is set to 3, but an option card is not installed in CN5, an oPE05 operation error will be displayed on the HOA keypad and the drive
will not run.
