Mitsubishi A800 FR-A862-05450 Instruction Manual

To perform a factory reset, access the inverter's parameter settings, locate the parameter for factory reset (usually parameter 79), and set it to the desired reset value. Refer to the user manual for detailed steps and precautions.
Begin by ensuring the power supply is disconnected. Mount the inverter securely, connect the power and motor wires according to the wiring diagram, and set the necessary parameters for your application. Always follow safety guidelines and consult the installation manual.
Check for sudden load changes or regenerative energy from the motor. Ensure the braking resistor is functioning correctly if installed. Verify the input voltage levels and adjust settings if necessary. Refer to the troubleshooting section of the manual for further guidance.
Regularly inspect for dust accumulation, ensure cooling fans are operational, check electrical connections for tightness, and monitor the inverter's temperature. Perform a comprehensive check every 6-12 months based on operational conditions.
Access the PID parameters through the inverter's interface or software, adjust the proportional, integral, and derivative settings according to your process requirements, and fine-tune as needed to achieve stable control. Consult the manual for parameter codes and examples.
The Mitsubishi A800 series is primarily designed for three-phase motors. Using it with a single-phase motor is not recommended and could lead to improper operation or damage. Consider a drive specifically designed for single-phase motors.
Firmware updates require connecting the inverter to a computer with Mitsubishi's software tools. Follow the instructions provided by Mitsubishi to download and install the latest firmware. Ensure that the inverter is not operating during the update process.
Determine the communication protocol (e.g., Modbus, Ethernet), configure the inverter's communication parameters, and connect it to the network as per the system requirements. Use Mitsubishi's software tools for advanced configuration and diagnostics.
Connect the external keypad using the dedicated port on the inverter, ensuring compatibility with the model. Configure any necessary parameters to enable external control. Refer to the user manual for detailed connection diagrams and settings.
Inspect the motor and load for mechanical issues or obstructions. Check the inverter's settings for current limits and adjust if needed. If the problem persists, consult the inverter's troubleshooting guide or contact technical support.
