Communication Option Card Code Number Fault

Was bedeutet CPF22 ?

An unrecognizable option board is connected to the control board, indicating a type mismatch or an unsupported option card. This prevents the drive from correctly interfacing with the option card, leading to functional limitations or failure.

• An incorrect or incompatible communication option card inserted into the drive's option slot.
• The drive's main control board firmware version is too old to recognize a newer option card.
• The option card is damaged internally, preventing its correct identification code from being read.
• Poor electrical connection between the option card and the main control board, preventing proper ID recognition.
