 b1-02: Run Command Selection 1
Parameter b1-02 determines the Run command source 1 in the REMOTE mode.
Setting 0: Digital Operator
This setting will illuminate the LO/RE light to indicate that the Run command source is assigned to the digital operator
(b1-02 = 0). Use the digital operator RUN and STOP keys to start and stop operation.
Setting 1: Digital input terminals
This setting requires that the Run and Stop commands are entered from the digital 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, presets the terminals S1 and S2 to
these functions. This is the default setting of the drive. Also refer to Setting 40, 41: Forward run, Reverse run
command for 2-wire sequence on page 242.
• 2-wire sequence 2:
Two inputs (Start/Stop-FWD/REV). Also refer to S
etting 42, 43: Run and direction command for 2-wire sequence 2
on page 242.
• 3-wire sequence:
Three inputs (Start-Stop-FWD/REV). Initialize the drive by setting
A1-03 = 3330 presets the terminals S1, S2, and S5
to these functions. Also refer to Setting 0: 3-Wire Sequence on page 236.
Setting 2: MEMOBUS/Modbus Communications
To issue a Run command via serial communications, set b1-02 to 2 and connect the RS-485/422 serial communication
cable to control terminals R+, R-, S+, and S- on the removable terminal block. Refer to MEMOBUS/Modbus
Communications on page 545 for instructions.
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.
 b1-03: Stopping Method Selection
Select how the drive stops the motor when the Run command is removed or when a Stop command is entered.
Setting 0: Ramp to stop
When the Run command is removed, the drive will decelerate the motor to stop. The deceleration rate is determined by
the active deceleration time. The default deceleration time is set to parameter C1-02.
When the output frequency falls below the
level set in parameter b2-01, the drive will start DC injection, Zero Speed
Control or Short Circuit Braking, depending on the selected control mode.
