(1) When power is cycled, if all conditions are present after power is restored, restart occurs.
(2) If all conditions are present when [Sleep-Wake Mode] is “enabled,” the drive starts.
(3) The active speed reference. The Sleep/Wake function and the speed reference can be assigned to the same input.

(5) Command must be issued from HIM, TB or network.
(6) Run Command must be cycled.
(7) SleepWake Ref Sel signal does not need to be greater than the wake level.
(8) SleepWake Ref Sel signal does not need to be less than the wake level.
