Specifications

Fuji's 4-pole standard motor When selecting an inverter, in addition to considering the kWs of the inverter, make sure that the output current rating is larger than the motor current rating.

Rated capacity is calculated by assuming the rated output voltage as 220 V for 200 V series and 440 V for 400 V series.

Output voltage cannot exceed the power supply voltage.

Voltage unbalance(%) =Max. voltage (V) - Min. voltage (V) / Three-phase average voltage (V) ×67 (IEC 61800-3)
If this value is 2 to 3%, use an optional AC reactor (ACR).

These values are calculated on assumption that the inverter is connected to a power supply with a capacity of 500 kVA (or 10 times the inverter capacity when the inverter capacity exceeds 50 kVA) and %X is 5%.

This is the average braking torque value for the motor on its own. (This will vary based on the motor efficiency.)

The interphase voltage unbalance ratio of the inverter power supply is 0% (at rated output).
