The certificate of the standard product is managed by the branch office. Please ask the nearest branch office. More Details >>

Selection method of the reactor

For the use of the 400 V class inverter, the surge voltage suppression filter FR-ASF is provided to suppress the surge voltage occurred at the motor terminal... More Details >>

Inverter control power supply

The FR-E540 uses common input for the control power supply and main circuit power supply. (It has only one power supply input terminal.) Therefore, you canno... 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 >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... 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 >>

Controlling multiple VVVFs via communication from personal computer

To control multiple inverters using arbitrary signals (4 to 20 mA) simultaneously, it is recommended to connect the signals (4 to 20 mA) in series. (This doe... More Details >>

Auxiliary input power supply

If you connect two frequency setting potentiometers to the terminals 5 and 10, the permissible current of 10 mA is exceeded, and you need to install 2 KΩ res... More Details >>
