140 YASKAWA ELECTRIC SIEP C710606 10A YASKAWA AC Drive - V1000 PRELIM. Programming Manual
Setting 0: 3-Wire Sequence
When one of the digital inputs is programmed for 3-wire control, that input becomes a
forward/reverse directional input, S1 becomes the Run command input, and S2 becomes the
Stop command input.
The drive will start the motor when the Run input S1 is closed for longer than 50ms. The
drive will stop the operation when the Stop input S2 is released for a brief moment.
Whenever the input programmed for 3-wire sequence is open, the drive will be set for
forward direction. If the input is closed, the drive is set for reverse direction.
Note: When 3-wire sequence is selected the Run and Stop command must be input at S1 and S2.
