Programming 71
Function: 3-Wire Control
Setting: 0
When one of the digital inputs is programmed for 3-Wire control, that input becomes a Forward/Reverse directional input. Whenever the
input is open, the Drive will be set for forward rotation of the motor shaft. If the input it closed, then the motor shaft will rotate in the
reverse direction whenever a there is a Run input. The S1 and S2 digital inputs will function as a Run and Stop input respectively.
