FAQ

What is the main difference between the HFC-VWS series and modern Hitachi inverters like the WJ200?

Modern inverters like the WJ200 are significantly more compact, offer more advanced control algorithms (like sensorless vector control), have built-in safety features (STO), and support modern industrial communication protocols like EtherNet/IP or Profinet, which are absent in the HFC-VWS series.

Can this inverter be operated without the built-in digital operator station?

Yes, the HFC-VWS series typically includes terminal blocks for external control signals. You can wire push buttons, potentiometers, and PLC outputs to control start/stop, direction, and speed reference remotely.

What should I check before powering up this vintage 1992 inverter for the first time?

For any VFD of this age that has been in long-term storage, it is highly recommended to ‘reform’ the main DC bus capacitors. This involves gradually applying DC voltage to restore the dielectric layer and prevent capacitor failure upon full power-up. If this is not possible, a visual inspection for leaking or bulging capacitors is crucial.
