Mitsubishi Electric A 800 Specification

The Mitsubishi Electric A800 series represents a state-of-the-art range of variable frequency drives (VFDs) designed to deliver superior performance, flexibility, and reliability in industrial automation applications. Engineered for robust performance, the A800 series supports a wide power range, accommodating motors from fractional horsepower up to 1000 HP. It offers advanced vector control technology, which ensures precise motor control and energy efficiency, enhancing operational productivity across diverse applications such as conveyors, fans, pumps, and compressors.

The A800 series is equipped with an intuitive, user-friendly interface that facilitates easy setup and programming, featuring an LCD display that provides clear feedback and diagnostics. Its built-in PLC functionality enables seamless integration with existing automation systems, reducing the need for additional hardware and lowering overall system costs. The VFD is designed with advanced safety features, including safe torque off (STO) and emergency stop functions, ensuring compliance with international safety standards.

Connectivity is a key feature of the A800 series, with support for a wide range of communication protocols such as Ethernet/IP, Modbus TCP, and CC-Link, allowing for easy integration into various industrial networks. Its robust design includes protection against harsh environments, with an IP20 or optional IP55 enclosure rating, ensuring reliable operation even in challenging conditions. The drive's energy-saving capabilities are further enhanced by its regenerative braking function, which captures and reuses energy typically lost during braking.

Incorporating Mitsubishi's renowned quality and innovation, the A800 series is designed to meet the demands of modern industrial environments, offering a comprehensive solution that balances performance, efficiency, and ease of use.

Mitsubishi Electric A 800 F.A.Q.

How do I reset the Mitsubishi Electric A800 drive to factory settings?

To reset the A800 drive to factory settings, navigate to the "Initial Setting" menu, select "All Clear," and confirm the reset. This will restore all parameters to their default values. Ensure that you document any custom settings before performing this action.

What is the procedure for troubleshooting an overcurrent fault on the A800?

First, check for any mechanical binding in the motor. Inspect the motor connections and cables for damage. Verify that the drive parameters match the motor's specifications. If the problem persists, reduce the acceleration time or increase the current limit settings.

How can I perform regular maintenance on the Mitsubishi Electric A800 inverter?

Regular maintenance includes inspecting the cooling fans and heatsinks for dust accumulation, checking electrical connections for tightness, and monitoring the condition of the capacitors. Perform these checks every 6 to 12 months to ensure optimal performance.

What steps should I take if the A800 drive is not powering up?

Ensure that the power supply is connected correctly and that the incoming voltage is within the specified range. Check the input fuses and circuit breakers for any faults. Inspect the drive for visible damage. If the issue persists, consult the manual or contact technical support.

How do I configure the Mitsubishi A800 drive for remote operation?

To configure the drive for remote operation, set the control mode to "External" and connect the remote control signals to the appropriate terminals. Configure the input terminals to match the remote control commands using the parameter settings.

What are the common causes of communication errors in the A800 drive?

Common causes include incorrect communication settings, faulty cables, or electromagnetic interference. Verify the baud rate, parity, and stop bits settings. Ensure that cables are properly shielded and grounded.

How can I update the firmware on the Mitsubishi Electric A800?

Download the latest firmware from the Mitsubishi Electric website. Transfer the firmware file to the drive using the compatible software provided by Mitsubishi. Follow the instructions in the manual to complete the update process.

What should I do if the drive displays a 'Parameter Error'?

Check the parameter settings to ensure they are within the allowable range. Look for any recently modified parameters that might be incorrect. Reset the parameter to its default value if necessary.

How do I adjust the acceleration and deceleration times on the A800 drive?

Access the parameter settings menu and locate the acceleration (ACC) and deceleration (DEC) parameters. Adjust these values based on the application's requirements for smoother operation.

Can the A800 drive be used with different types of motors?

Yes, the A800 drive supports various motor types, including induction, synchronous, and PM motors. Ensure that the drive's parameters are configured to match the specific motor type you are using.
