4.6 Basic Drive Setup Adjustments
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the frequency reference via the RS-485//RS-422 serial communications port (control terminals
R+, R-, S+, 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.
Setting 4: Pulse Train Input
This setting requires a pulse train signal to terminal RP to provide the frequency reference. Follow the directions below to
verify that the pulse signal is working properly.
Verifying the Pulse Train is Working Properly
• Set b1-01 to 4 and set H6-01 to 0.
• Set the H6-02 to the pulse train frequency value that equals 100% of the frequency reference.
• Enter a pulse train signal to terminal RP and check for the correct frequency reference on the display.
n b1-02: Run Command Selection 1
Determines the Run command source 1 in the REMOTE mode.
No.
b1-02
Setting 0: Operator
This setting will illuminate the LO/RE light to indicate that the Run command source is assigned to the digital operator. Use
the digital operator RUN and STOP keys to start and stop operation.
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:
Setting A1-03 to 2220 initializes the drive and presets terminals S1 and S2 to FWD/Stop and REV/Stop. These are the default
settings of the drive.
• 2-Wire sequence 2:
Two inputs (Start/Stop-FWD/REV).
• 3-Wire sequence:
Setting A1-03 to 3330 initializes the drive and presets terminals S1, S2, and S5 to Start, Stop, and FWD/REV.
Setting 2: MEMOBUS/Modbus Communications
This setting requires entering the Run command via serial communications by connecting the RS-485/RS-422 serial
communication cable to control terminals R+, R-, S+, and S- on the removable terminal block.
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-A port on the control PCB. Refer to the option board manual 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 operation error will be displayed on the digital operator and
the drive will not run.

b1-03: Stopping Method Selection
Selects how the drive stops the motor when the Run command is removed or when a Stop command is entered.
No.
