

Restart mode after momentary power failure (Allowable momentary power failure time) (H16)

H16 specifies the maximum allowable duration (0.0 to 30.0 seconds) from an occurrence of a momentary power
failure (undervoltage) until the inverter is to be restarted. Specify the coast-to-stop time which the machine system
and facility can tolerate.

If the power is restored within the specified duration, the inverter restarts in the restart mode specified by F14. If
not, the inverter recognizes that the power has been shut down and the inverter does not apply the restart mode.

If H16 (Allowable momentary power failure time) is set to "999," restart will take place until the DC link bus voltage
drops down to the minimum allowable voltage for restart after a momentary power failure (50 V for 230 V series
and 100 V for 460 V series). If the DC link bus voltage drops below the allowable voltage, the inverter recognizes
that the power has been shut down and does not restart.

230 V series

50 V

460 V series

100 V

The time required from when the DC link bus voltage drops from the threshold of undervoltage until it
reaches the allowable voltage for restart after a momentary power failure greatly varies depending on the
inverter capacity, the presence of options, and other factors.



Restart mode after momentary power failure (Restart time) (H13)

H13 specifies the time period from momentary power failure occurrence until the inverter reacts for restarting

process.
If the inverter starts the motor while motor’s residual voltage is still in a high level, a large inrush current may flow
or an overvoltage alarm may occur due to an occurrence of temporary regeneration. For safety, therefore, it is
advisable to set H13 to a certain level so that the restart will take place only after the residual voltage has dropped
to a low level. Note that even when power is restored, restart will not take place until the restart time (H13) has
elapsed.
