Specifications

*1

Rated capacity is calculated by regarding the output rated voltage as 440 VAC.

*2

Output voltage cannot exceed the power supply voltage.

*3

These values correspond to the following conditions: carrier frequency is 10 kHz (2 phase modulation) and ambient temperature is 45°C. Select the inverter capacity such that the square average current during operation is not higher than the 80% of the rated current of the inverter.

*4

Voltage unbalance [%] = (Max.voltage [V] - Min.voltage [V])/ Three-phase average voltage [V] x 67(IEC61800-3). Just for 3ph 400 VAC input supply case.

*5

The power supply capacity is 500kVA (ten times the inverter capacity when the inverter capacity exceeds 50kVA), and the value of the power supply impedance is %X=5%.

*6

The admissible error of minimum resistance is ±5%.

*7

Braking time and duty cycle (%ED) are defined by cycle operation at the rated regenerative power.

*8

Variations (Voltage: +10 to -10%, Frequency: +5 to -5%)
