| *1 | Fuji 4-pole standard motor |
| *2 | Rated capacity is calculated by assuming the output rated voltage as 220V for three-phase 200V series and 440V for three-phase 400V series. |
| *3 | Output voltage cannot exceed the power supply voltage. |
| *4 | When the carrier frequency is low, the temperature of the motor may increases rapidly or the inverter protection (current limit) may activate. When setting the carrier frequency to 1kHz or less, reduce the load to 80% of its rated value. |
| *5 | The value is calculated on assumption that the inverter is connected with a power supply capacity of 500kVA (or 10 times the inverter capacity if the inverter capacity exceeds 50kVA) and %X is 5%. |
| *6 | Average braking torque without optional braking resistor (Varies with the efficiency of the motor.) |
| *7 | Voltage unbalance (%) = ( MAX. voltage(V) - Min. voltage(V) ) / ( Therr-phase average voltage(V) ) x 67 (compliant with IEC61800-3) If this value is 2 to 3%, use an AC REACTOR (ACR option). |
| *8 | It is used as an AC fan power supply input for applications combined with a high power-factor PWM converter with power regeneration function or the like (not used during normal operation). |
| *9 | Use the inverter at the current given in ( ) or below when the carrier frequency setting is higher than 3kHz or the ambient temperature is 30°C or higher. |
