Item Explanation
0.00 to 6000 s
，
Linear/S-curve/curvilinear, Acceleration/deceleration time settings 1 to 4 switchable.
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)
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.
Settable Current limiting action value
Over current limiting by hardware (it can be canceled)
Terminals AFM: Output a selected signal with DC voltage (0 to +10 V) or DC current (4 to 20 mA)
Terminals DFM:Output a selected signal with pulse (25 to 6000p/s log voltage (0 to +10 V)

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).
