12.8 H: Terminal Function Selection
YASKAWA SIEPC71061753C GA500 Technical Manual 629
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.
WARNING! Sudden Movement Hazard. When you use a 3-Wire sequence, set A1-03 = 3330 [Initialize Parameters = 3-Wire
Initialization] and make sure that b1-17 = 0 [Run Command at Power Up = Disregard Existing RUN Command] (default). If you
do not correctly set the drive parameters for 3-Wire operation before you energize the drive, the motor can suddenly rotate
when you energize the drive.
