FR-F740-00023-EC Variable Frequency Drive FR-F 0.7kW 3-ф/380

FR-F740-00023-EC is a Mitsubishi Electric FR-F variable frequency drive rated at 0.7 kW (3-phase 380 V input, 3-phase 380 V output). We use it for a small pump, fan, or process extraction unit when the project needs Mitsubishi hardware, clear diagnostics, and 110-130% overload headroom.

• Current: 2.3 A, IP20, maximum frequency 120 Hz.
• What matters: Here the brake module is listed as built in, with RS-485 and basic PID.
• Check before use: Before commissioning, check motor current, terminal wiring, and the required control method.

Mitsubishi Electric FR-F: where this series fits

FR-F is a series for pumps, fans, compressors, and HVAC. Our catalog currently has 55 active items in this series, from 0.7 to 315 kW, supply variants 3x380, and IP20, 54 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-F

• Common mechanisms: pump stations, ventilation, compressors, and smoke extraction.
• 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-F inside the Mitsubishi range

When FR-F is not the right drive

We do not recommend FR-F for positioning or heavy constant-torque work where FR-A is the better fit. 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.
