Note:

1. The applicable motor refers to the capacity applicable to a 4-pole Mitsubishi Electric standard motor when in use.

2 rated output capacity, 230V for 3-phase 200V level and 440V for 3-phase 400V level.

The rated% value of the overload current is relative to the rated output current of the frequency converter. When reusing, wait for the frequency converter and motor to return to a temperature below the load.

The output voltage is not higher than the power supply voltage. The output voltage can be changed within the set range. However, the peak value of the voltage waveform on the output side of the frequency converter is about √ 2 times the power supply voltage.

The magnitude of the braking torque is the short-term average torque of the motor unit at a short speed limit of 60Hz (based on changes in motor losses), not continuous regenerative torque. When the frequency deceleration exceeds the fundamental frequency, the value of the average deceleration torque will decrease. Because the frequency converter does not have a built-in braking resistor, please use the optional braking resistor (0.1K, 0.2K cannot be used) when the regenerative energy is high. The brake unit (FR-BU2) can also be used.

The capacity of the power supply equipment varies due to the value of the impedance on the power supply side (including input reactors and wires).

When the ambient temperature exceeds 40 ℃ and the Pr.72 PWM frequency is set above 2kHz for low-noise operation, the rated output current is within ().

The value at which the rated input current is equal to the rated output current. The rated input current varies due to the impedance of the power supply side (including the input reactor and wires).
