Setting 0: 3-Wire Sequence
The digital input programmed for 3-Wire control becomes the forward/reverse directional input, S1 becomes the Run command
input, and S2 becomes the Stop command input.
The drive starts the motor when the input S1 set for the Run command closes for longer than 2 ms. The drive stops the operation
when the Stop input S2 is released. When the digital input programmed for a forward/reverse operation is open, the drive is
set for forward operation. When the digital input is closed, the drive is set for reverse operation.
Note: Input the Run and Stop commands via S1 and S2 when selecting a 3-Wire sequence.

Note: 1. The Run command must be closed for more than 2 ms.
2. If the Run command is active at power up and b1-17 = 0 (Run command at power up not accepted), the Run LED will flash to indicate
that protective functions are operating. If required by the application, set b1-17 to 1 to automatically issue the Run command upon drive
power up.
WARNING!
Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before applying
power to the drive. Failure to comply could result in death or serious injury from moving equipment.
WARNING!
Sudden Movement Hazard. The drive may start unexpectedly in reverse direction after power up if it is wired for 3-Wire sequence
but set up for 2-Wire sequence (default). Make sure b1-17 is set to “0” (drive does not accept a Run command active at power up). When
initializing the drive use 3-Wire initialization. Failure to comply could result in death or serious injury from moving equipment.
