What to do if CUTES Inverter shows 'OC' or 'OCS' during operation?
- G
  George FryAug 15, 2025
  If the CUTES Inverter displays 'OC' or 'OCS' during operation, which indicates an overcurrent, it could be due to a short circuit or grounding in the motor's U.V.W connections. You should exclude any short circuits or grounding. Alternatively, an instantaneous mechanical load on the motor could be the cause, requiring you to reduce the load or increase the inverter capacity. The motor itself may have broken down and need repair. In rare cases, the inverter itself may be faulty, requiring you to contact the manufacturer.

What to do if CUTES CT-2000ES Inverter displays 'OU' during operation?

  If your CUTES Inverter displays 'OU' during operation, it indicates an overvoltage condition. First, verify that the power voltage is within the specified range and improve the power voltage condition if necessary. Also, consider applying a braking resistor and increasing the braking ratio if one is not already in use. Finally, check if the deceleration time is too short for the load; if so, lengthen the deceleration time by applying Code 09 and Code 11.

How to troubleshoot a CUTES Inverter when the motor does not run?

  Tracy StaffordAug 21, 2025
  If the motor connected to your CUTES Inverter doesn't run at all, several issues could be the cause. First, check for any wiring errors by referring to the wiring diagram, ensure the power input wiring is correct, and verify the presence of voltage for the U.V.W output. If the wiring is correct, examine the settings on the operator panel, specifically function code No.04, to ensure it's set correctly for either panel key operation (0) or external signals (1). Also, make sure that the inverter does not display a fault indication. If overload is the reason, exchange the motor for a higher capacity one. If the motor is broken, repair it. If the inverter itself has broken down, contact the manufacturer.

What does 'PLU' mean on a CUTES CT-2000ES and how to fix it?
- Y

  If the CUTES Inverter displays 'PLU' during operation, start by checking if the power voltage meets the specified requirements and improve the power voltage condition if necessary. Also, check the capacity of the power facilities to address any instantaneous power voltage failures or instances where the power has dropped and the protector function has activated.

Why does my CUTES CT-2000ES display 'OL' and how can I resolve it?
- L
  Laura AllenAug 31, 2025
  If the CUTES Inverter displays 'OL' during operation, this indicates an overload condition. You should reduce the load or increase the inverter capacity. Additionally, check if the inverter's overcurrent limiter is appropriately set by applying Code 06 to reset the motor's rated current.

What causes 'OCPd' on a CUTES CT-2000ES Inverter during deceleration?
- J
  John WalkerSep 4, 2025
  If the CUTES Inverter displays 'OCPd' as the motor decelerates, it means there's an overcurrent during deceleration. This is likely because the deceleration time is too short for the load. To resolve this, apply Code 09 and Code 11 to lengthen the deceleration time, or increase the inverter capacity.

What does 'OH' mean on my CUTES CT-2000ES Inverter and how do I fix it?
- D
  daughertymarySep 7, 2025
  If the CUTES Inverter displays 'OH' during operation, start by checking if the cooling fan is still working. If not, replace the cooling fan and clean any accumulated dirt. Also, evaluate whether the ambient temperature is too high and improve the ambient temperature condition if necessary.

What to do if CUTES CT-2000ES has no indication and output frequency is '0'?
- D
  Daniel LoveSep 12, 2025
  If there is no indication on your CUTES Inverter, and the output frequency displays '0', it could be due to a power failure. Check the capacity of the power facilities. Also, check the external control terminal to see if there is a loosen part.

What to do if CUTES CT-2000ES shows 'OCPA' on motor start?
- M
  Melissa RobertsNov 24, 2025
  If the CUTES Inverter displays 'OCPA' as soon as the motor starts, indicating an overcurrent during acceleration, several factors could be responsible. Begin by checking the motor wiring for any errors, referring to the wiring diagram. Ensure that the inverter and motor terminals (U.V.W) are not shorted or grounded, and correct any such issues. Reduce the load or increase the inverter capacity if there's an overload. Check if the V/F slope is appropriate for the motor specification by checking Code 05. Adjust Code 07 torque boost to overcome steady friction without causing an overcurrent trip. Lengthen the acceleration time using Code 08 and Code 10, or increase the inverter capacity if the acceleration time is too short for the load GD2. Lastly, if the inverter is starting during motor fr...
