How to fix overcurrent (OC) error on Omron Inverter?
- A
  alvarezjuanAug 20, 2025
  If your Omron Inverter displays an overcurrent (OC) error, it indicates a potential issue. This could be due to a short-circuit or ground fault at the Inverter output, in which case you should check and correct the motor power cable. It may also be caused by an incorrect V/f setting, so try reducing the V/f set voltage. If the motor capacity is too large for the Inverter, reduce the motor capacity to the maximum permissible. If the magnetic contactor on the output side of the Inverter has been opened and closed, rearrange the sequence so that the magnetic contactor will not open or close while the Inverter has current output. As a last resort, the output circuit of the Inverter may be damaged, requiring you to replace the Inverter.

Why is my Omron SYSDRIVE 3G3MV Inverter radiation fin overheated (OH)?
- D
  danallisonAug 25, 2025
  If your Omron Inverter displays a 'Radiation fin overheated (OH)' error, it could be due to several factors. First, check if the ambient temperature is too high; if so, ventilate the Inverter or install a cooling unit. An excessive load could also cause overheating, so reduce the load. Additionally, an incorrect V/f setting might be the issue, requiring you to reduce the V/f set voltage. If the acceleration/deceleration time is too short, increase it. Obstructions to ventilation can also lead to overheating, so change the location of the Inverter to meet the installation conditions. Lastly, if the cooling fan of the Inverter isn't working, replace it.

What causes main circuit undervoltage (UV1) on Omron SYSDRIVE 3G3MV Inverter?
- P
  pfordAug 27, 2025
  If you're encountering a 'Main circuit undervoltage (UV1)' error on your Omron Inverter, several factors could be responsible. Check for phase loss in the power supply, loose power input terminal screws, or a disconnected power cable. Ensure the power supply voltage is correct and within specifications. If a momentary power interruption has occurred, use the momentary power interruption compensation by setting n081 to allow the Inverter to restart after power is restored. If none of these resolve the issue, the internal circuitry of the Inverter may be damaged, requiring a replacement.

What should I do if my Omron Inverter is overloaded (OL2)?
- C
  Crystal HarperAug 30, 2025
  If your Omron Inverter displays an 'Inverter overload (OL2)' error, consider these potential causes: The load might be excessive, so try reducing it. An incorrect V/f setting could also be the issue; in this case, reduce the V/f set voltage. If the acceleration/deceleration time is too short, increase it. If the Inverter capacity is insufficient for your application, consider using an Inverter model with a higher capacity.

Why is my Omron SYSDRIVE 3G3MV Inverter showing overtorque detection (OL3)?
- L
  Lisa KaiserSep 1, 2025
  If you're getting an 'Overtorque detection (OL3)' error on your Omron Inverter, it could be due to a locked or failed mechanical system; check the mechanical system and correct the cause of overtorque. Incorrect parameter settings can also trigger this error; adjust the n098 and n099 parameters according to the mechanical system.

What does Digital Operator transmission fault 1 (F00) mean on Omron SYSDRIVE 3G3MV Inverter?
- J
  Justin HuffmanSep 3, 2025
  If your Omron Inverter is showing a 'Digital Operator transmission fault 1 (F00)' error, it could be due to a few reasons. First, the Digital Operator may not be mounted properly, so turn OFF the Inverter, dismount and mount the Digital Operator, and turn ON the Inverter. If that doesn't work, the Digital Operator itself might have a failure, requiring you to change it. In some cases, the Inverter itself may have a failure, necessitating a replacement.

What to do for control power supply undervoltage (UV2) error on Omron SYSDRIVE 3G3MV Inverter?
- N
  Nathaniel VillarrealSep 7, 2025
  If your Omron Inverter displays a 'Control power supply undervoltage (UV2)' error, an internal circuit fault might be the cause. Try turning the Inverter OFF and then ON again. If the same fault occurs again, replace the Inverter.

What does initial memory fault (F04) mean on Omron Inverter?
- J
  Jack HubbardSep 9, 2025
  If your Omron Inverter is showing an 'Initial memory fault (F04)' error, it indicates a fault within the internal circuitry of the Inverter. Initialize the Inverter with n001 set to 8 or 9, then turn the Inverter OFF and ON. If the same fault persists, replace the Inverter.
