Keypad Connection Fault

What does oPr mean?

This fault indicates that the keypad is either not securely connected to the drive or its connection cable is damaged or disconnected. It specifically triggers if keypad disconnect detection is enabled (o2-06=1) and the run command is from the keypad or the drive is operating in LOCAL mode with the keypad. An insecure connection prevents proper control and monitoring of the drive.
