• 2-wire Sequence 2
This sequence allows for two types of input: Run/Stop and FWD/REV.
• 3-Wire Sequence
This sequence allows for three types of input: Run, Stop, and FWD/REV. Setting A1-03 = 3330 [Initialize
Parameters = 3-Wire initialization] and initializing the drive sets terminals S1, S2, and S5 for a 3-wire
sequence.
2 : Memobus/Modbus Communications
Enter the Run command by using MEMOBUS/Modbus communications, which comes standard with the drive.
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 for installation and communications settings.
Note:
If b1-02 = 3 is set and an option card is not connected, then oPE05 [Run Cmd/Freq Ref Source Sel Err] will flash on the keypad.

(01C6)
0 : Disregard existing RUN command
The drive does not start operating the application when the power is switched ON, even if the Run command is
already enabled.
Re-enter the Run command to have the drive operate the application.
Note:
For safety, the drive is set so that it will not start operating the application when the power is switched ON, even if the Run command is
already enabled. The
the power is switched ON.
1 : Accept existing RUN command
The drive starts operating the application when the power is switched ON if the Run command is already enabled.
WARNING! Sudden Movement Hazard. When using a 3-Wire sequence, set the drive to 3-Wire sequence and set b1-17 = 0
[Run Command at Power Up = Disregard Existing RUN Command] before wiring the control terminals so the drive will not
accept a Run command at power up. The motor may rotate in reverse when the drive is powered up if the drive is wired for a 3-
wire sequence but set up for a 2-wire sequence (default) and b1-17 = 1 [Accept Existing RUN Command]. Failure to comply
could cause death or serious injury from moving equipment.
