Description

Designed for demanding heavy-duty industrial environments, the FR-A740-15K-CHT represents a high-performance Variable Frequency Drive (VFD) from the Mitsubishi Electric FR-A700 series. This three-phase AC inverter module provides exceptional motor control accuracy and high torque output, specifically engineered to optimize the operation of induction motors up to 15 kW. Featuring advanced real sensorless vector control and vector control capabilities, it delivers precise speed and torque regulation across a wide operating range, making it ideal for cranes, lifters, extruders, and conveyor systems.

The unit features a robust hardware construction with built-in regenerative braking options and forced air cooling to maintain thermal efficiency. Designed for seamless system integration, this drive supports various industrial network communication protocols and features extensive programmable input/output configurations to match complex automation architectures.

Features

• Advanced Real Sensorless Vector Control (RSV) for high torque at zero speed.
• Exceptional overload tolerance of 150% for 60 seconds and 200% for 3 seconds.
• Integrated EMC filter to minimize high-frequency electromagnetic emissions.
• Enclosed IP20 protective structure suitable for standard control cabinet installations.
• Forced air cooling system ensures reliable continuous duty performance.

Applications

Installation Guidelines

• Mounting Position: Always install the drive vertically on a flat, non-flammable surface to facilitate optimal air convection.
• Clearance Requirements: Ensure a minimum clearance of 50 mm on both sides and 100 mm above and below the unit for proper heat dissipation.
• Grounding: Connect the protective earth terminal strictly to a low-impedance ground to prevent electromagnetic interference and electric shock.
• Environmental Limits: Protect the unit from direct sunlight, corrosive gases, flammable materials, and fine conductive dust.

Compliance and Certifications

• CE (European Conformity)
• UL Listed / cUL
