ride-through control Possible to keep the motor running using its
regenerative energy in case of a momentary power failure (default: OFF).
Auto-restart operation In the event of a momentary power failure,
the inverter reads the rotational speed of the coasting motor and
outputs a frequency appropriate
to the rotational speed in order to restart the motor smoothly.
This function can also be used when switching to commercial power.

machine by increasing the rotational speed of the motor when it is
operated under light load.

please set the filter of 10ms or more, or timer for
measures when connecting it directly with input unit terminal of programmable controller. Please use the OUT terminal as much as
possible when the programmable controller is connected.
Note 3. Current must be reduced by 1% for each 100 m over 1000 m. For example, 90% at 2000m and 80% at 3000m.
Note 4. When using the inverter in locations with temperatures above 40°C, remove the protective label on the top of the
inverter and use the inverter with the output current reduced according to the instruction manual.
. To align the inverters side-by-side horizontally, remove the protective label on the top of the inverter before use.
When using the inverter in locations with temperatures above 40°C,
use the inverter with the output current reduced.
