function.
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the frequency reference via the RS-485 serial communications port (control terminals R+,
R-, S+, and S-). Refer to MEMOBUS/Modbus Communications on page 513 for instructions. For details, refer to the
FSDrive-MV1000 Instruction Manual (Manual No. EZZ010926).
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 an option board (b1-01 = 3), but an option board is not installed, an OPE05 Operator
Programming Error will be displayed on the digital operator and the drive will not run.

Setting 1: Control Circuit Terminal
This setting requires that the Run and Stop commands are entered from the contact input terminals. The following
sequences can be used:
• 2-wire sequence 1:
Two inputs (FWD/Stop-REV/Stop). Initializing the drive by setting A1-03 = 2220, assigns the Forward Run Command
(2-wire Sequence) function (H1-
Sequence) function (H1-
drive. Also refer to Setting 40, 41: Forward run, Reverse run command for 2-wire sequence on page
• 2-wire sequence 2:
Two inputs (Start/Stop-FWD/REV). Also refer to
2 on page 173.
Setting 2: MEMOBUS/Modbus Communications
To issue a Run command via serial communications, set b1-02 to 2 and connect the RS-485 serial communication cable
to control terminals R+, R-, S+, and S- on the removable terminal block. For instructions, refer to the FSDrive-MV1000
Instruction Manual (Manual No. EZZ010926).
Setting 3: Option card
To issue the Run command via the communication option board, set b1-02 to 3 and plug a communication option board
into the CN5-A port on the control PCB. Refer to the manual supplied with the option board for instructions on
integrating the drive into the communication system.
Note: If b1-02 is set to 3, but an option board is not installed in CN5-A, an oPE05 operator programming error will be displayed on the
digital operator and the drive will not run.
