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. Refer
to Multi-Step Speed Selection on page 52 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-). Refer to MEMOBUS/Modbus Configuration on page 280 for instructions.
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.

No. Parameter Name Setting Range Default
b1-02 Run Command Selection for AUTO Mode 1 to 3 1
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. Refer to Setting 40, 41: Forward Run, Reverse Run Command for 2-
Wire Sequence on page 84 .
• 2-Wire sequence 2:
Two inputs (Start/Stop-FWD/REV). Refer to Setting 42, 43: Run and Direction Command for 2-Wire Sequence 2 on
page 84 .
• 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 79 .
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. Refer to MEMOBUS/Modbus
Configuration on page 280 for instructions.
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.
