Keypad Communication Fault

What does 52 mean?

The connection between the control panel (keypad) and the drive is defective, preventing proper communication. This could be due to a faulty cable, improper seating of the keypad, or a damaged control panel itself. Loss of communication means the drive cannot be controlled or monitored via the keypad.
