Cpf
There are two types of CPF faults. CPF00 will happen if communication between the drive and the digital operator is not established within 5 seconds of supplying power. CPF01 will happen if communication is started and then subsequently lost for more than 2 seconds.
There are really only two possible faults here. Either the digital operator is no longer functioning or the control board has failed.
Check that the digital operator is firmly seated. Remove it and reinstall it. Cycle power to the machine. If the error still comes back, you have a fault and will have to determine how to proceed.
You can repair the individual components or replace the entire inverter.
