 FR-A860-00680 or higher

The applicable motor capacity indicated is the maximum capacity applicable for use of the 4-pole standard motor.

The rated output capacity indicated assumes that the output voltage is 575 V.

When an operation is performed with the carrier frequency set to 3 kHz or more, and the inverter output current reaches the value indicated in the parenthesis, the
carries frequency is automatically lowered. The motor noise becomes louder accordingly.

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.

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 .

Value for the ND rating

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.

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).
