FR-A840-45K-1 MITSUBISHI Variable Frequency Inverter -10℃~+400℃ DC 600V

FR-A840-45K-1 Description

FR-A840-45K-1 Features

• Advanced Magnetic Flux Vector Control:​ Delivers high-performance control comparable to servo systems, offering 150% starting torque at 0.3 Hz (with optional encoder feedback), enabling precise control in applications like centrifuges, extruders, and test stands.
• Energy Saving Optimization:​ Built-in energy-saving algorithms automatically adjust voltage and frequency to minimize motor input power based on the real-time load, leading to significant reductions in electricity costs, especially in variable torque applications like fans and pumps.
• Enhanced Robustness & Reliability:​ Features reinforced internal components, a corrosion-resistant coating on the PCB, and a durable design to withstand harsh industrial environments with high humidity, dust, and vibrations. It also includes a built-in EMC filter for reduced electromagnetic interference.
• Intelligent Functions:​ Equipped with a wide array of features such as PLC-like built-in sequence control (with optional function block programming), predictive maintenance functions (monitoring of lifetime for cooling fan and capacitors), and advanced safety functions (Safe Torque Off - STO compliant with SIL3/PL e, via optional module).
• User-Friendly & Flexible:​ Features a detachable keypad for easy programming and remote operation. The front cover can be rotated for flexible installation. It supports multiple communication protocols via optional plug-in cards (CC-Link, PROFIBUS, PROFINET, EtherNet/IP, Modbus, etc.).
• All-in-One Protection:​ Comprehensive protection features for both the drive and motor, including overload, overvoltage, undervoltage, ground fault, short circuit, and overheating protection.
