Drive hardware not ready to operate

What does 4650 mean?

The drive hardware is not in a ready state for operation. This can be caused by the drive being in a hardware error state, still undergoing its start-up phase (which can take several seconds after a reset), or missing the necessary controller enable signal. Until the drive is ready, no motion commands can be executed.
