Fault output terminal load pattern

The fault output terminals A and C, and B and C of the power regeneration converter FR-RC are not capable of a micro load of 5 VDC±5%, 10 mA. The minimum loa... More Details >>

AC reactor and line noise filter wiring

Basically, either is OK.Both orders are electrically identical, but "1" is recommended since it is preferable to place the line noise filter close to the inv... More Details >>

When controlling motor with brake by inverter

Use the RUN signal to turn ON and OFF the brake.Using the MRS (output shutoff) signal to turn ON the brake shuts off the inverter's output and reduces influe... More Details >>

Surge voltage of 400 V inverter

1. Since the voltage resistance of the standard motor is not improved, it is recommended to use an "insulation-enhanced motor".If you are using an insulation... 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 >>

Operation of automatic restart after instantaneous power failure

1. No operation log is recorded.2. No. However, you can create a state indicating that automatic restart after instantaneous power failure is in progress by ... More Details >>

Coasting to stop method

Use Pr.17 (Input terminal assignment) to assign MRS to the terminals DI1, DI2, and DI3. 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 >>

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>
