Mitsubishi Electric FR-A800-E Ethernet Inverters Review: Specs, Price and Applications
Mitsubishi Electric FR-A800-E adds an integrated Ethernet interface to the FR-A800 inverter platform. The supplied listing identifies 100 Mbit/s connectivity, Modbus/TCP and CC-Link IE Field Network Basic, with maintenance and parameter access through FR Configurator2. The Ethernet suffix identifies a communication configuration; motor current and power still follow the selected inverter code.
Quick Verdict
A relevant variable-frequency-drive option when standard Ethernet communication simplifies the required machine architecture. Define control ownership, stop behavior and maintenance access along with the motor duty.

Design and Engineering Assessment
A 100 Mbit/s physical link is not a guaranteed motion-control update period. Actual command behavior depends on the protocol, controller scan, network loading and the inverter’s selected control mode.
Network parameter access can simplify servicing without making direct public-Internet exposure appropriate. Establish which controller commands the drive, how maintenance changes are controlled and what the machine does after a communication interruption.
Sizing the Motor-and-Drive System
A variable-frequency drive should be sized around motor current, supply class and the required overload cycle. A nominal power figure is a useful starting point, but motor nameplate current and the machine’s repeated acceleration or load changes determine the practical requirement. The selected drive must also support the intended motor type and control method. Similar kW ratings do not make every drive-and-motor pairing equivalent.
Consider the machine’s low-speed operating condition as carefully as its maximum speed. Motor cooling and the required torque can change with speed, particularly when the motor relies on a shaft-mounted fan. The selected motor and drive arrangement must support that duty rather than treating a wide command-frequency range as proof that full rated torque is continuously available everywhere.
Electrical Installation and Control
The electrical design includes the incoming supply, protection, grounding, motor cable and any required filtering or braking components. A drive is part of that installation rather than a substitute for it. For a retrofit, preserve the approved motor connection and assess the existing cable system before applying a new control platform.
Deceleration can raise the DC-bus voltage as the load returns energy. A high-inertia machine needs a defined braking or regeneration arrangement appropriate to its stopping cycle. The process controller also needs a clear sequence for enable, speed reference, controlled stopping and fault recovery. A network option must be matched to the PLC’s actual communication and drive profile.
Commissioning and Acceptance
Enter the correct motor data and establish conservative current, acceleration and deceleration limits before testing the full process. Check rotation direction and the machine’s behavior during starting, stopping and interruption of the speed reference. Evaluate the system under representative load and ambient conditions, because an unloaded spin does not demonstrate the required thermal duty.
Keep the qualified parameter set with the motor and drive ordering information. For maintenance, record the control source, motor data, ramp settings and fault-handling behavior. If a selected model includes a safety function such as STO, integrate it according to the machine’s defined safety architecture; it is not electrical isolation and does not automatically brake a moving load.
Applications and Selection
Industrial motor-speed control and coordinated machine systems requiring compatible Ethernet drive communication.
For Mitsubishi Electric FR-A800-E Ethernet Inverters, define the actual machine duty before selecting an ordering configuration. Include the required operating point, available installation space, environment and control interfaces. The specification table describes the product or family; the surrounding machine determines which of those features matters for the intended job.
Price and Value
Price: Request a quote for the exact configuration. Compare the product, compatible control equipment, required mechanical parts, cabling and commissioning as one installed system. A component price alone does not represent the cost of a working automation axis.
Evaluate an alternative against the same duty and acceptance criteria. Match the continuous operating requirement first, then compare transient capability, feedback, mechanical fit and support. This avoids choosing between superficially similar products whose ratings describe different operating conditions.
Pros and Cons
Advantages
Ethernet communication without a separate basic Ethernet option card
Parameter and diagnostic access through the manufacturer software
Limitations
Interface capability does not establish the motor-current rating
Network command and recovery behavior need explicit configuration
