Regenerative power
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.
Light-load high-speed operation Increases the operating efficiency of the machine by increasing the rotational speed of the motor when it is operated under light load.
Drooping function When two or more inverters are used to operate a single load, this function prevents load from concentrating on one inverter due to unbalance.

Note 1. Maximum output voltage is the same as the input voltage.
Note 2. It is necessary to finely adjust Bias and Gain parameters of each analog input.
Note 3. A chattering (momentary ON/OFF of contact) is generated by external factors of the vibration and the impact, etc. In particular, 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 4. Current must be reduced by 1% for each 100 m over 1000 m. For example, 90% at 2000m and 80% at 3000m.
Note 5. 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 section 6.18 in user 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.
