*1
Indicates the maximum capacity applicable to voltage of 575 V.
*2
The rated output capacity indicated assumes that the output voltage is 575 V.
*3
Possible output currents during continuous operation under Real sensorless vector control or Vector control are shown in the table below.
PWM carrier frequency
SLD
1 kHz 230 A
2 kHz 191 A
3 kHz 154 A
4 kHz 115 A
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 6 kHz or more (Pr. 72
*4
The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time for the
inverter and motor to return to or below the temperatures under 100% load.
*5
The 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.
*6
Built-in brake transistor model only. For the resistance, refer to the FR-A870 Instruction Manual (Hardware).
*7
The 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.
*8
The 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).
