Description
The Mitsubishi FR-E740-5.5K is a compact, high-performance 5.5kW (7.5 HP) Variable Frequency Drive (VFD) from the widely trusted Mitsubishi Electric E700 Series. Built to regulate speed and torque for 3-phase AC induction motors, it delivers robust engineering capabilities within a small physical footprint to optimize panel space.
Driven by Mitsubishi’s proprietary Advanced Magnetic Flux Vector Control algorithm, the FR-E740-5.5K provides powerful low-speed starting torque and stable velocity response under fluctuating load conditions. For textile factories, packaging plants, processing facilities, and HVAC systems across Bangladesh, this drive ensures enhanced production throughput, lowered energy consumption, and maximum protection for mechanical motor drives.
Key Features
- Advanced Magnetic Flux Vector Control: Delivers up to 200% torque output at ultra-low frequencies (0.5Hz) for heavy starting loads without requiring motor encoders.
- Compact Enclosure Footprint: Delivers maximum power density in a space-saving housing structure for efficient control cabinet design.
- Integrated Safety Functionality: Incorporates Safe Torque Off (STO) hardware inputs for reliable emergency stop safety compliance.
- Built-in Modbus-RTU & USB Communication: Features RS-485 Modbus-RTU port and mini-USB terminal for fast parameter copying and PC software tuning via Mitsubishi FR Configurator.
- Overload Protection Capacity: Supports heavy-duty overload ratings (150% for 60 seconds, 200% for 0.5 seconds) to buffer peak startup torque surges.
Technical Advantages
- High Efficiency: Modern power switching circuitry minimizes thermal dissipation and internal electrical losses.
- Durable Construction: Protective conformal PCB coating guards circuit boards against humidity, moisture, and chemical particulate accumulation.
- Safety Protection: Integrated protective logic guards against overcurrent, overvoltage, short circuit, earth fault, phase loss, and thermal overload.
- Energy Saving: Dynamic excitation control automatically optimizes output voltage under partial motor loads to lower electricity costs.
- Easy Maintenance: Features removable terminal boards and quick-disconnect cooling fans for rapid servicing and minimal maintenance downtime.
Applications
- Industrial & Manufacturing: Industrial conveyor belts, extruders, mixers, agitators, and automatic packaging machines.
- Factory Automation: Textile spinning/weaving equipment, paper convertors, and plastic processing machinery.
- Commercial Facilities: HVAC supply and exhaust fans, cooling tower fans, water booster pumps, and centrifugal blowers.
- Project Installation: Industrial control panels, motor control centers (MCC), and retrofitting projects built by system integrators across Bangladesh.

Installation & Maintenance Guide
Installation Requirements:
- Mount vertically inside an IP54-rated, well-ventilated electrical control panel to shield against airborne dust, oil, and lint.
- Maintain recommended top, bottom, and side clearances around the inverter enclosure for adequate heat dissipation.
- Connect a dedicated 3-phase earth ground and use shielded control cabling to prevent electromagnetic interference (EMI).
Maintenance Tips:
- Clean dust buildup off cooling fans and heat sink fins regularly using dry, low-pressure compressed air.
- Inspect electrical terminal connection screws at scheduled maintenance intervals to prevent loose wiring due to machine vibration.
- Review fault diagnostic logs via the digital keypad or software tools during routine plant maintenance checks.
Safety Instructions:
- Disconnect incoming AC mains power and wait a minimum of 10 minutes for internal DC capacitors to fully discharge before opening wire covers.
- Electrical installation, parameter tuning, and commissioning must be carried out by trained electrical technicians or engineers.
