On the FR-A800\FR-F800, what is USB port used for?

The mini B connector is used for connecting with FR Configurator2. A USB memory device can be connected to the A connector (host) to save parameters or trace data or to copy parameters from one A800/F800 to another A800/F800. Parameters can be copied from one to...

Can the Ethernet IP communication control the FR-A800?

Yes. the options support it. By connecting the following communication option (built-in circuit board) manufactured and sold by HMS to the FR-A800 series, the FR-A800 can be supported by the communication protocol of the Ethernet IP. HMS model: A8NEIP_2P...

When the power supply of the main circuit and control circuit is separated, does the undervoltage warning occur if the power failure occurs only at the main circuit? (Under the condition where power at the rated voltage is continually supplied to the control power supply)When the main circuit is normal and the control power supply is OFF, does the under voltage warning occur by the time the capacitor runs out of charge?

The Undervoltage warning of the inverter is judged based on the voltage of the main circuit as follows. Power failure only at the main circuit: Output an Undervoltage warning power failure only at the control circuit. Not output an Undervoltage warning when the...

What is a VFD?

A VFD (Variable Frequency Drive), also referred to as a VSD (Variable Speed Drive), inverter or drive, is a piece of hardware that is used to control the speed of an AC Induction motor. This is achieved by the VFD controlling the Frequency output (Hz) (in conjunction...

What is the difference between a VFD and a VSD?

Nothing. Both terms are used for describing drive inverters. They are prominently being used interchangeably, depending on the manufacturer of the country. (For Mitsubishi FA, the term VFD is mostly used.). VSD (Variable Speed Drive) refers to the motor shaft...

Can I use a VFD as a voltage converter?

In one word, no. A VFD cannot be used as a replacement for a voltage transformer. If a motor requires 400Vac, then a 400Vac source is required as an input to the 400Vac VFD. The same goes for other voltage classes, The only exception to this rule is with phase number....

What type of VFD Inverter drives are there?

The FREQROL VFD inverter drive series are available in the following flavors: FR-CS80 – Compact type: Entry-level inverter FR-D700 – Compact type: Compact \ standard FR-E700 \ FR-E800 – Modular type: All-rounder. FR-F800 – Modular type:...
