Mitsubishi Electric FR frequency inverters: which series to choose

Mitsubishi Electric drives are sold under the FREQROL brand, hence the FR prefix in series names. The catalogue has five series: from compact FR-D and FR-E to FR-A for demanding machinery and FR-F for pumps and fans up to 315 kW. The table below is a good starting point for selection.

Main Mitsubishi Electric series

FR-D: compact series for simple tasks

Small footprint, easy installation and set-up. Single-phase 1×220 V models are available at 0.75, 1.5 and 2.2 kW; their output is three-phase 3×220 V. More: FR-D series.

FR-E: general-purpose series for medium power

Sensorless magnetic flux vector control, Modbus RTU. Single-phase models at 0.75–2.2 kW and three-phase 380 V up to 22 kW. More: FR-E series.

FR-A: series for demanding machinery

The series covers FR-A740 (A700 generation) and FR-A840 (A800 generation). Sensorless vector control, high overload capacity; encoder-based vector control works with an optional card. Range up to 315 kW. Suited to machine tools, winders, extruders and lifting equipment. More: FR-A series; FR-A840 models at 0.75–30 kW are also grouped separately: FR-A840.

FR-F: series for pumps and fans

Optimised for pump and fan loads, with a built-in PID controller and pump control functions. Range up to 315 kW, the largest series in the catalogue. More: FR-F series.

How to choose a Mitsubishi inverter

We first check motor power and current, then load type, cable length and control method. To replace an old drive, a photo of the motor nameplate and of the old inverter's nameplate is enough for an engineer to pick a match. If Mitsubishi is more than the job needs, consider INVT, Veichi or Delta.

Other Mitsubishi Electric equipment

For control cabinets we also supply Mitsubishi PLCs and MELSERVO servo drives. Brand overview and all product lines: Mitsubishi Electric in Ukraine.

Frequently Asked Questions

Which frequency inverter converts 380 to 220 V?

The question hides a trap. A drive with a single-phase 220 V input feeds the motor 3×220 V, not 380. We keep six such Mitsubishi units: FR-D720S and FR-E720S at 0.75, 1.5 and 2.2 kW. A 380 V three-phase motor will run from them if its nameplate shows the 380/220 V Y/Δ pair: you move the links in the terminal box to delta and the windings get their 220 V. Rated torque stays, current is 1.7 times higher. Motors from 4 kW up are usually wound for 380/660 V, and there this trick no longer works.

Who manufactures Mitsubishi?

Mitsubishi Electric Corporation, Tokyo. Their drive range carries the FREQROL trade name, which is where the FR prefix in model numbers comes from. The European -EC versions we stock come through Mitsubishi Electric Europe. We hold 134 models, priced from UAH 14,400 with VAT. Official warranty is 24 months from the date of purchase.

What is a frequency inverter?

A power device sitting between the mains and the motor. Inside there is a rectifier first, then a DC capacitor link, then an IGBT output stage that builds the required sine wave by PWM out of the fixed 50 Hz supply. The point is simple. The motor runs at the speed you set instead of its single nameplate speed. At Mitsubishi that job belongs to the FR family, from FR-D at 0.75 kW up to FR-F at 315 kW.

How does a frequency inverter work?

Three stages. The rectifier turns mains AC into DC, the DC link smooths it with capacitors, and the IGBT output stage chops it back into three-phase AC at the frequency you want. The drive holds the U/f ratio itself so that motor flux stays within limits. In FR-D and FR-E this is scalar plus sensorless vector control. FR-A adds Real Sensorless Vector with 150% overload for 60 seconds, which is why it goes onto cranes.

How do I set up a frequency inverter?

On Mitsubishi the order is this. Motor nameplate data and thermal protection current first, then acceleration and deceleration times, and only after that Pr. 79: control from the keypad, from terminals or over Modbus. Terminal functions live in Pr. 180-186, where STF is forward run, STR is reverse and RL/RM/RH are preset speeds. A full FR-D700 and FR-E700 walkthrough sits as a separate guide in our instructions section. For a specific model, write to us and our engineers will advise.

What are frequency inverters used for?

Three reasons. Energy saving on pumps and fans, where flow is trimmed by speed rather than by a damper. A soft start with no inrush current, so the breaker stays in and the belt survives. And process control: a conveyor at a set speed, a crane without a jolt, a machine tool at the spindle rpm you need. FR-F is usually fitted on pumping stations, FR-D and FR-E on machine tools and conveyors.
