Plug-in option

A plug-in option cannot be installed on the FREQROL-A024 series. If you need a plug-in option's function, use other series of inverters such as the FREQROL-A... More Details >>

Compatibility of the installation between FR-A200EXCELLENT and FR-A200?

Yes. (However, since they are aligned with the small size of the FR-A200 (D), you need to use the intercompatibility attachment FR-AAT for a larger size. Att... More Details >>

CC-Link

Yes, but the optional kit (FR-A7NC E kit) is necessary. More Details >>

Second deceleration time setting

Your suggestion is fine, but note that deceleration stop is naturally not available in case of an inverter error.In addition, considering regenerative power,... More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>

Proper use of AC reactor and DC reactor

1. ACL has the input power factor of approximately 90% and DCL has the input power factor of approximately 95%. Therefore, DCL has a higher input power facto... More Details >>

EMC compliant filter terminal cover

The SF1258 has the terminal cover.Although the SF1259 to SF1263 do not have the terminal covers and their terminals are bare, rubber tubes to cover them are ... More Details >>

Rated capacity related to harmonic suppression guidelines

The usual inverter input current is determined not by the inverter capacity but by the motor capacity (motor load).Therefore, the input side capacity is not ... More Details >>
