Stuck Key Error (Adv. Code 0)

What does 29 mean?

This fault is triggered if the drive detects a persistent key press during power-up. This can be caused by a faulty keypad button or a user inadvertently holding a key down while powering on the drive. This prevents proper initialization and operation via the keypad.
