Mitsubishi Electric Frequency Inverters

Mitsubishi Electric frequency inverters (FR-500, FR-700, FR-800 series) are designed for precise control of asynchronous and permanent-magnet motors. They regulate motor speed, torque, and acceleration, optimizing energy consumption and improving the reliability of drive systems.

These inverters are used across all industrial sectors — from pump and fan stations to conveyor systems, production lines, and HVAC automation — wherever stable and efficient motor control is required.

Technical Excellence and Global Standards

Over seven million Mitsubishi Electric drives are in operation worldwide.
Each device is built in accordance with international standards:
CE, UL, CUL, GOST and marine certifications.

Compliance with these standards simplifies global equipment integration and ensures reliability under demanding operating conditions.

Performance Features

• Power range from 0.2 to 630 kW for both constant-torque and variable-torque loads
• Overload capacity up to 200% for short-term peak demands
• Automatic restart and flying-start for rotating motors
• Integrated braking control and dynamic torque response
• Online auto-tuning for stable speed under load fluctuations
• Soft PWM modulation for reduced audible noise and motor heating
• Built-in PID controller for process control loops
• Vector-control algorithms for high torque at low speeds

Energy Optimization

Mitsubishi Electric drives are known for their energy-saving algorithms.
The Optimum Excitation Control (OEC) function reduces magnetic flux during light load conditions, lowering energy consumption by up to 10 % without affecting torque. For large installations with multiple motors, this results in significant cost savings and extended equipment life.

Communication and Integration

All Mitsubishi Electric frequency inverters are ready for modern industrial networks, including Profibus-DP, DeviceNet, CC-Link, CANopen, and Modbus-RTU.

Ethernet-based communication modules are available for higher-level SCADA and PLC integration.

The built-in control logic allows direct connection of sensors and actuators without an external PLC for small systems, providing flexible installation options and reducing system cost.

Reliability and Protection

Mitsubishi Electric drives continuously monitor output current and voltage.

In case of overload or short circuit, the inverter reacts within milliseconds, protecting both the drive and the motor. Standard protection functions include over-current, over-voltage, under-voltage, phase loss, and thermal protection.

Extended life components (long-life capacitors, reinforced cooling systems)
ensure continuous operation in 24/7 production environments.

Software and Configuration
