Mitsubishi FR-A800 Advanced Inverter

The Mitsubishi FR-A800 Advanced Inverter is Mitsubishi Electric's flagship general-purpose high-performance drive, delivering real sensorless vector control technology for demanding industrial applications that require fast dynamic response, high torque at low speed, and tight speed regulation without encoder feedback. Available from 0.4 kW to 90 kW on 400 V three-phase supply (FR-A840 series), the FR-A800 generates rated torque from 0.5 Hz in sensorless vector mode — enabling direct drive of heavily loaded conveyors, extruders, and winders from standstill without hunting or speed droop. Its speed response of 50 rad/s (sensorless) rivals the closed-loop performance of drives that require encoder feedback, significantly reducing installation cost on applications where fitting an encoder to the motor is impractical or expensive.

The FR-A800 integrates Mitsubishi's Advanced Magnetic Flux Vector control, which continuously estimates motor flux and adjusts voltage vector in real time to achieve torque ripple of less than 3% across the speed range. The built-in regenerative braking unit handles overhauling loads — crane hoists, inclined conveyors, centrifuge deceleration — returning energy to the DC bus rather than dissipating it in a brake resistor, improving overall system efficiency by up to 30% on high-cycle duty applications. Standard communication includes RS-485 Modbus RTU, with optional CC-Link IE Field Network, EtherNet/IP, PROFIBUS-DP, and PROFINET adapters available for direct integration into MELSEC PLC and third-party DCS architectures without gateway hardware.

Saudi Arabia's industrial modernisation under Vision 2030 is creating strong demand for high-performance drives in sectors ranging from automotive assembly at Al-Jubail manufacturing parks, to plastics and rubber processing in Riyadh industrial cities, to mining and minerals at Ma'aden phosphate and aluminium facilities in Al-Ba'itha. The FR-A800's ability to handle demanding dynamic loads — rapid acceleration/deceleration cycles, variable torque profiles, and high overload during starting — makes it the natural upgrade path for facilities replacing ageing DC drives or first-generation inverters. Saudi Aramco engineering standards for motor control in process utility systems accept the FR-A800 as a qualified product, and Mitsubishi's local type-testing documentation supports SEC and SASO compliance requirements.

Razz Middle East provides the FR-A800 with full parameter engineering services, including application-specific motor characterisation, acceleration/deceleration ramp design, and multi-speed preset configuration. Our drive engineers hold Mitsubishi Electric FA product certifications and can commission FR-A800 systems at any Saudi site. SAR pricing with 18-month warranty is available within 4 hours of RFQ. Razz also offers preventive maintenance contracts covering annual drive inspection, parameter backup, and cooling fan replacement.
