I want to shorten deceleration time of small capacity motor

You can use an inverter with a larger capacity than the motor. You cannot connect a brake resistor to the FR-E520-0.1K and 0.2K. With the FR-E520-0.1K or 0.2... More Details >>

Noise filter

We offer DC reactors from 0.4K and you can use it. 　You can use FR-BIF, FR-BSF, and FR-BEL together. More Details >>

Relationship between frequency and load current

If the load is heavy and the output current is higher than the control value, you can adjust Pr.22 (Stall prevention operation level) to trigger the stall pr... More Details >>

Priority of multi-speed setting and frequency setting signals

For frequency setting, multi-speed setting is prioritized over current input. Therefore, when the multi-speed signal is input, the inverter switch to multi-s... More Details >>

Current measurement method

When measuring current, if you open the output side while current is flowing on the input side, high voltage is induced and dielectric breakdown may occur wi... More Details >>

Countermeasure against harmonics

When the high power factor converter is installed, you can use the conversion coefficient of K5 = 0 for calculation. In accordance with the harmonic suppress... More Details >>

Remote operation of the inverter

The wiring length of the start signal (STF etc.) is 30 m or less. The circuit voltage of the control input signals (terminal STF etc.) is 24 VDC and the volt... More Details >>

Advanced magnetic flux vector control and General-purpose magnetic flux vector control

Advanced magnetic flux vector control provides a larger torque at low-speed. 3.7K or lower: 0.5 Hz/200%5.5K to 15K: 0.5 Hz/150% More Details >>

Specifications

It can be driven by connecting single-phase 200 V to the terminals R and S. In this case, the load current must be one-third or less of the inverter rated cu... More Details >>
