The Mitsubishi FREQROL-A846 Series Variable Frequency Drive offers precise motor control for a wide range of industrial applications, with a durable IP55, NEMA 12 rated enclosure for protection against damp environments, and contaminants such as dirt and dust. Units feature a waterproof keypad for quick and easy set-up. This series offers a speed response of 50Hz, with a speed range of 200:1 open loop (1500:1 closed loop). The FR-A846 Series is built to support high speed motors up to 590Hz, including the new generation of IPM motor models. These drives feature STO functionality for SIL2/PLd category emergency stops, while conformal coated boards come standard for enhanced durability. DC Link chokes are provided for improved power quality, with an EMC filter for reduced radio noise levels.

The FR-A846 Series drive is available with 100Mbps Ethernet communication, enabling seamless connection to MODBUS TCP/IP and CC-Link IE Field Basic networks without the need for additional option cards. The built-in web server provides remote monitoring and parameter adjustment capabilities, while automatic IP address detection simplifies system setup using FR-Configurator2 software. USB stick compatibility allows for quick parameter adjustments and diagnostic data transfer.

The FR-A846 Series also feature connectivity with the GOT 2000 series HMIs, and an enhanced internal PLC based on Mitsubishi's L Series processor with Function Block programming support. The multiple protocol capability and drive-to-drive communications system offer flexible integration.
