OFF-to-ON transition signals the inverter that the
motor is already running at powerup (via bypass),
thus suppressing the inverter’s motor output in Run

ON-to-OFF transition signals the inverter to apply a
time delay (B003), frequency match its output to
existing motor speed, and resume normal Run Mode

(3-wire interface)
(3-wire interface)
ON
Selects the direction of motor rotation: ON = FWD.
While the motor is rotating, a change of F/R will start
a deceleration, followed by a change in direction.
While the motor is rotating, a change of F/R will start
a deceleration, followed by a change in direction.
OFF
Selects the direction of motor rotation: OFF =REV.
While the motor is rotating, a change of F/R will start
a deceleration, followed by a change in direction.

ON
Temporarily disables PID loop control. Inverter

OFF
Has no effect on PID loop operation, which operates
normally if PID Enable is active (A071 = 1).
