*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 กระแสs during continuous operation under Real sensorless vector การควบคุม or Vector การควบคุม are shown in the table below.

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 การควบคุม or Vector การควบคุม 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 กระแส rating indicated is the ratio of the overload กระแส to the inverter's rated output กระแส. For repeated duty, allow time for the inverter and motor to return to or below the temperatures under 100% load.

*5The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting ช่วง. 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 เบรก transistor model only. Use a เบรก 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 กระแส 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 กระแส.

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