<1> Number appearing in parenthesis is the default value after performing a 3-Wire initialization (A1-03 = 3330).
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 releases for 2 ms. 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.
