Installation method

If multiple line noise filters are wound without clearance between them, the noise reduction effect corresponding to the number of filters cannot be obtained... More Details >>

Difference between FR-AU01 and AU01A

The major changes from FR-AU01 to FR-AU01A include 1. Case material and 2. Lead wire terminal process method. The FR-AU01A has a backward compatibility with ... More Details >>

Using a higher grade power factor improving reactor

Using a reactor under a load lighter than the rated capacity slightly spoils its effect in improving the power factor.Therefore, you should use a reactor wit... More Details >>

Synchronous operation of two motors

When synchronously operating two motors, you need to detect speed from both motors. Each inverter is controlled based on this speed detection signal. As an e... More Details >>

Regenerative power flow

If all inverters are in regenerative operation, the regenerative power is regenerated to the power supply. If one of the inverters is power driving, the rege... More Details >>

FR-BSF-01

□□□□□□ Year Month (Control number) The last digit of the production year is indicated as the Year, and the Month is indicated by 1 to 9, X (October), Y (Nove... More Details >>

Influence on noise level

By using the reactors 1 and 2 as well as the outside box supplied with the high power factor converter, while the noise may increase or decrease depending th... More Details >>

FR-B3

The carrier frequency for the FR-B3 is 2 kHz. For the low noise type FR-B3-N, it is 14.5 kHz. More Details >>

FR-HC2

The internal transistor of the HC2 stops by turning on the SOF signal and stopping the converter. As a result, regenerative driving is not performed. However... More Details >>

What happens if the supplied reactor and outside box are not used?

Harmonics cannot be suppressed (controlled) correctly and noise cannot be removed. Be sure to connect the supplied reactor and outside box to the inverter. More Details >>
