When terminal S1 (Run command) activates for 1 ms minimum, the drive rotates the motor. When terminal S2
(Stop command) deactivates, the drive stops. When terminal Sx that is set in 3-wire sequence deactivates, the
drive operates in the forward direction, and when it activates, the drive operates in the reverse direction.
WARNING!
Sudden Movement Hazard. Set the MFDI parameters before you close control circuit switches. Incorrect Run/Stop
circuit sequence settings can cause serious injury or death from moving equipment.

do not correctly set the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate in
reverse when you energize the drive.
