FR-A740-00083-EC Variable Frequency Drive FR-A 2.2kW 3-ф/380

FR-A740-00083-EC is a Mitsubishi Electric FR-A variable frequency drive rated at 2.2 kW (3-phase 380 V input, 3-phase 380 V output). We use it for a small machine tool, feeder, or precision industrial drive when the project needs Mitsubishi hardware, clear diagnostics, and 150% overload headroom.

• Current: 6 A, IP20, maximum frequency 120 Hz.
• What matters: FR-A brings vector control, PID, RS-485, 12 digital inputs, and a built-in EMC filter.
• Check before use: Before commissioning, check motor current, terminal wiring, and the required control method.

Mitsubishi Electric FR-A: what this series is

FR-A is a premium series for machine tools, lines and high-torque drives. Power range in this selection is 0.75–315 kW, supply 3×380 V. Mitsubishi is chosen where service life, clear diagnostics and compatibility with Mitsubishi Electric automation matter.

When to choose FR-A

• Typical machines: CNC machines, winders, extruders, heavy-start conveyors and lifting equipment.
• Selection: we check motor power and current first, then load type, cable length and control method.
• Service note: for older cabinets, replacement without reworking terminals and parameters is often what matters.

FR-A in the Mitsubishi line-up

When FR-A is not the right fit

We do not recommend FR-A for an ordinary pump or fan, where FR-F or a cheaper INVT GD20 fits better. For such jobs INVT or Veichi are often enough, and for pumps also see pump inverters.

Selection and manuals

A photo of the motor nameplate is enough before ordering. Wiring and parameters: FR-D700 and FR-E700 set-up, error codes. All series: Mitsubishi Electric frequency inverters.
