If the CUTES Controller displays 'OU' during operation, it could be due to the power voltage not matching the specification. You should improve the power voltage condition. Alternatively, a braking resistor might not be applied. In this case, apply a braking resistor and increase the braking ratio.
What to do if 'PLU' is displayed during CUTES CT-2004-3A7 operation?
If the CUTES Controller displays 'PLU' during operation, it could be due to the power voltage not matching the specification, so you should improve the power voltage condition. It may also be caused by an instantaneous power voltage failure or power drop, in which case you should check the capacity of the power facilities.
What to do if 'OL' is displayed during CUTES CT-2004-3A7 operation?
If 'OL' is displayed during CUTES Controller operation, it could be due to an overload. Try reducing the load or increasing the inverter capacity. It could also be because the inverter over current limiter is not appropriate. In this case, apply Code 06 to reset the motor rated current.
What to do if 'OH' is displayed during CUTES CT-2004-3A7 operation?
If 'OH' is displayed during CUTES Controller operation, check if the cooling fan is still working. If not, change the cooling fan and clean any dirt. Also, check if the ambient temperature is too hot and improve the ambient temperature condition if needed.
What to do if CUTES CT-2004-3A7 Controller inverter starts during motor free-run?
If the CUTES Controller inverter is starting during motor free-run, it is likely that the deceleration time is too short and unable to be loaded. Change the value from 0 to 1 by referring to Code 28. You can also apply Code 09 and Code 11 to lengthen the deceleration time or increase the inverter capacity.
How to troubleshoot a CUTES CT-2004-3A7 when the motor does not run?
If the CUTES Controller motor does not run at all, it could be due to a wiring error. Refer to the wiring diagram, check the power input wiring, and verify if there is a voltage for the U.V.W output. Alternatively, it could be due to wrong settings at the operator panel. Ensure the function code No.04 is set correctly: 0 for Panel key operation, 1 for External signals.
What to do if CUTES CT-2004-3A7 shows no indication and output frequency is 0?
If there is no indication and the output frequency displays '0' on your CUTES Controller, it could be due to a power failure. Check the capacity of the power facilities. Also, check for any loose parts on the external control terminal.
