Item Explanation
Stop control
• Running continued at the stop frequency, coast-to-stop, or force to stop.
• DC braking: Braking starting frequency (up to 60 Hz), time (up to 30.0 s), and operation level
(up to 100%)
• Zero speed control (under vector control with speed sensor.)
Auto-restart after
momentary power failure
• Trip immediately, trip after recovery from power failure, trip after deceleration to stop
• Continue to run, restart at the frequency at which the power failure occurred, restart at the
starting frequency, restart after searching for idling motor speed

Other features
Protection against
momentary power failure
Upon detection of a momentary power failure lasting more than 15 ms, this function stops the
inverter output. If restart after momentary power failure is selected, this function invokes a restart
process if power is restored within a predetermined period (allowable momentary power failure
time).
