Mitsubishi F800-E FR-F842-07700-355K Inverter F.A.Q.

What are the initial steps to set up the Mitsubishi F800-E FR-F842-07700-355K Inverter?

Ensure the inverter is correctly mounted and wired. Power on the device, access the parameter settings, and configure the basic parameters such as motor capacity, voltage, and operation mode according to the motor specifications. Refer to the user manual for detailed guidance.

How can I troubleshoot an overcurrent fault in the Mitsubishi F800-E inverter?

Check for short circuits or ground faults in the motor and cables. Verify that the motor is not jammed or overloaded. Ensure that the inverter parameters are set according to the motor’s rated specifications. Reset the inverter and monitor for recurring faults.

What is the recommended maintenance schedule for the F800-E inverter?

Perform a visual inspection every three months, clean the cooling fan and heatsinks, and check for loose connections. Annually, conduct a detailed electrical inspection and test all safety features. Replace cooling fans every 3-5 years, depending on the usage environment.

How do I reset the inverter to factory settings?

To reset the inverter to factory settings, access the parameter menu and select the 'All Clear' option. Confirm the operation when prompted. Note that this will erase all custom settings, so ensure you back up any necessary parameters before performing this action.

What does the 'E.OC1' error code indicate and how can it be resolved?

The 'E.OC1' error code indicates an overcurrent during acceleration. Check for motor overload or mechanical binding. Ensure that the acceleration time is appropriately set and adjust if necessary. Inspect the motor and inverter connections for any faults.

How can I improve energy efficiency using the F800-E inverter?

Utilize the inverter’s energy-saving functions such as automatic energy-saving operation and optimal excitation control. Properly size the inverter for the motor load and adjust the operation to match the demand. Regular maintenance also ensures efficient operation.

Can the inverter be controlled remotely, and what setup is required?

Yes, the F800-E inverter can be controlled remotely via communication options such as RS-485 or Ethernet. Configure the communication parameters in the inverter settings and ensure the appropriate protocol is selected. Connect to a compatible PLC or control system for remote operation.

What should I do if the inverter does not start the motor?

Check that the inverter is powered on and that the start command is being received. Verify that all necessary interlocks and safety circuits are closed. Inspect the parameter settings to ensure they are correctly configured for the motor.

How do I program a deceleration time for the inverter?

Access the parameter settings and locate the deceleration time parameter (usually P2 or similar). Enter the desired deceleration time in seconds. Ensure that the value set is appropriate for the application to prevent overvoltage conditions.

What precautions should be taken when installing the inverter in harsh environments?

Ensure the inverter is housed in an appropriate enclosure to protect against dust, moisture, and corrosive elements. Maintain adequate ventilation and cooling. Use cable glands and seals to prevent ingress and consider using additional filters for electrical noise.
