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: where this series fits

FR-A is a premium series for machines, production lines, and high-torque drives. Our catalog currently has 14 active items in this series, from 0.7 to 55 kW, supply variants 3x380, and IP20 enclosures. We use Mitsubishi where price is not the only criterion: service life, readable diagnostics, and Mitsubishi Electric automation compatibility matter.

Typical jobs for FR-A

• Common mechanisms: CNC machines, winders, extruders, and conveyors with heavy starts.
• Selection: first check motor power and current, then load type, motor cable length, and the control method.
• Retrofit note: in older cabinets, replacement without rebuilding terminals and parameters often matters more than the drive price.

FR-A inside the Mitsubishi range

When FR-A is not the right drive

We do not recommend FR-A for a basic pump or fan where FR-F or INVT GD20 is the more sensible spend. In those cases INVT or Veichi is often enough, and pump projects should also start from VFDs for pumps.

Our field note

Customers rarely buy Mitsubishi by accident. It is usually a FREQROL replacement, a cabinet with MELSEC/GOT, or a production line where downtime costs more than the price difference. Before payment we ask for a motor nameplate photo and a cabinet diagram. Fewer surprises at startup.
