2.3 b: Application
Use the control circuit terminals to enter the Run command. Select the input method for the Run command with an
H1-xx parameter.
Set H1-xx = 0, 40 to 43 [3-Wire Sequence, Run Command (2-Wire Sequence)]. The default setting is 2-wire sequence
1.
• 2-wire Sequence 1
This sequence has two input types: FWD/Stop and REV/Stop. Set A1-03 = 2220 [Initialize Parameters = 2-Wire
Initialization] to initialize the drive and set terminals S1 and S2 for a 2-wire sequence.
• 2-wire Sequence 2
This sequence has two input types: Run/Stop and FWD/REV.
• 3-Wire Sequence
This sequence has three input types: Run, Stop, and FWD/REV. Set A1-03 = 3330 [Initialize Parameters = 3-Wire
Initialization] to initialize the drive and set terminals S1, S2, and S5 for a 3-wire sequence.
2 : Memobus/Modbus Communications
Use MEMOBUS/Modbus communications to enter the Run command.
3 : Option PCB
Use a communications option card or input option card connected to the drive to enter the Run command.
Refer to the instruction manual included with the option card to install and set the option card.
Note:
If b1-16 = 3 but no option card is connected, then oPE03 [Multi-Function Input Setting Err] will flash on the keypad.

b1-17 Run Command at Power Up
(01C6)
0 : Disregard Existing RUN Command
The drive does not start to operate the application when the power is switched ON, even when there is an existing Run
command.
Enter the Run command again to operate the application.
Note:
When you energize the drive,
1 : Accept Existing RUN Command
When there is an existing Run command, the drive starts to operate the application when the power is switched ON.
WARNING! Sudden Movement Hazard. When you use a 3-Wire sequence, set A1-03 = 3330 [Initialize Parameters = 3-Wire
Initialization] and make sure that b1-17 = 0 [Run Command at Power Up = Disregard Existing RUN Command] (default). If you do
not correctly set the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate in reverse
when you energize the drive.

0 : Reject RUN if b2-01<U1-05<E1-09
If the motor speed ≥ b2-01 or the motor speed < E1-09, the drive will not accept a Run command.
1 : Accept RUN Command at Any Speed
If the motor speed ≥ b2-01 or the motor speed < E1-09, the drive will accept a Run command.

V/f CL-V/f OLV CLV AOLV
Sets drive response when energizing a drive that has an external Run command. Set this parameter in
applications where energizing or de-energizing the drive enables the Run command.
on the keypad will flash quickly if the Run command is already enabled from an external source.
V/f CL-V/f OLV CLV AOLV
Sets the conditions for the drive to accept a Run command when A1-02 = 3, 7 [Control Method
Selection = CLV, CLV/PM]. Usually it is not necessary to change this setting.
