Terminal Board Connection Error

What does CPF08 mean?

There is a faulty connection between the terminal board and the control board. This critical connection is necessary for processing all input/output signals (e.g., start/stop commands, speed references, fault outputs). A poor connection can lead to unreliable control, intermittent operation, or a complete lack of response from the drive, affecting machine safety and performance. This fault may also indicate an EEPROM serial communication fault within the terminal board itself.
