Keypad Connection Fault

What does oPr mean?

This fault indicates that the keypad is not securely connected to the drive's connector or that the connection cable is damaged or disconnected. This fault triggers when keypad disconnect detection is enabled (o2-06=1) and the drive is configured for keypad run command (b1-02=0) or is operating in LOCAL mode. A faulty connection prevents proper drive control and monitoring, impacting operational safety and efficiency.
