is maintaining a “Start” or “Jog” command without sending a “Stop command”, the drive will start
automatically when power is cycled.

P106 [Start Source] is set to option 3, and the Run input is maintained, the
Run inputs do not need to be toggled after a Stop input for the drive to run
again. A Stop function is provided only when the Stop input is active (open).
