*1Values in the "690 VAC power input" table indicate the maximum applicable motor capacity at a power input of 690 V. Values in the "575 VAC power input" table indicate the one at a power input of 575 V.

*2Values in the "690 VAC power input" table indicate the maximum capacity at an inverter output of 690 V. Values in the "575 VAC power input" table indicate the one at an inverter output of 575 V.

*3Possible output currents during continuous operation under Real sensorless vector control or Vector control are shown in the table below.

PWM carrier frequency	02300		02860
PWM carrier frequency	SLD	ND	SLD	ND
2kHz	191A	159A	237A	198A
4kHz	115A	107A	143A	133A

The PWM carrier frequency is automatically decreased to 2 kHz for heavy duty applications when operating the motor under Real sensorless vector control or Vector control with a PWM carrier frequency of more than 6 kHz (Pr.72 ≥ 6). The carrier frequency stays at 4 kHz in fast-response operation.

*4The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. Para un servicio repetido, espere a que el inversor y el motor regresen a la temperatura con una carga del 100 % o a una temperatura inferior.

*5The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However, the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about √2.

*6The built-in brake transistor model only. Use a brake resistor of 4 Ω or more. Power consumption at 4 Ω measures 291,6 kW with an input of 690 VAC, and 220,4 kW with an input of 575 VAC.

*7The rated input current indicates a value at a rated output voltage. The impedance at the power supply side (including those of the input reactor and cables) affects the rated input current.

*8The power supply capacity is the value when at the rated output current. It varies by the impedance at the power supply side (including those of the input reactor and cables).
