Constant-torque duty — not just a fan pump drive
The FR-A840-00126-2-60 is rated for constant-torque duty covering both moderate and heavy-duty profiles. That means it handles conveyors, extruders, mixers, and positive-displacement pumps — loads where torque demand stays flat across the speed range — not just variable-torque fan or centrifugal pump applications. Rated 3.7 kW at 9 A continuous output on a 400/415 V three-phase supply. The 9 A figure is the drive's continuous current rating at the rated voltage; match it to a motor nameplate full-load current at or below this value for proper thermal protection.
Panel fit and IP20 chassis
IP20 means open-chassis construction; the drive must be installed inside a suitable enclosure with at least IP54 ingress protection for the overall assembly, per the installation manual.
A800 series positioning
This drive belongs to Mitsubishi's A800 series — the general-purpose high-performance drive family supporting plug-in option slots for fieldbus (CC-Link, PROFIBUS, EtherCAT), encoder feedback, and extended I/O. The series is positioned between the entry-level D700 and the high-end F800 for servo-like applications.
