Description
The Mitsubishi FR-E740-0.4K is a compact, high-performance 0.4kW (0.5 HP / 400W) Variable Frequency Drive (VFD) from Mitsubishi Electric’s FREQROL-E700 Series. Built to regulate the speed, torque, and power output of small 3-phase AC induction motors, it delivers advanced vector control capabilities within a compact housing that optimizes panel space.
Operating on a 380V to 480V 3-phase supply with a rated output current of 1.6A and an output frequency range of 0.2 to 400Hz, the FR-E740-0.4K provides steady speed stability and dynamic starting torque. Equipped with conformal-coated circuit boards and Modbus-RTU communications, this drive is ideal for garment machinery, small packaging setups, conveyors, commercial appliances, and HVAC automation in Bangladesh, ensuring reduced utility costs and extended motor lifespan.
Key Features

Installation & Maintenance Guide
Installation Requirements:
- Install vertically inside an IP54-rated, well-ventilated electrical control panel to shield against airborne dust, lint, and oil mist.
- Retain recommended vertical and horizontal clearances around the drive housing for unrestricted cooling airflow over the heat sink.
- Ground the unit using a dedicated 3-phase earth ground wire and use shielded cables for control signals to prevent electromagnetic interference (EMI).
Maintenance Tips:
- Periodically clear dust accumulation from heat sinks and cooling paths using dry, low-pressure compressed air.
- Inspect terminal block screw tightness at scheduled intervals to prevent loose connections caused by machine vibration.
- Monitor diagnostic alarm codes on the front control panel or via Modbus-RTU software during routine plant maintenance checks.
Safety Instructions:
- Always disconnect incoming 3-phase AC power lines and wait at least 10 minutes for internal DC capacitors to discharge completely before touching wiring terminals.
- Electrical installation, parameter programming, and commissioning must be carried out by qualified electrical engineers or technicians.
