Follower communication

What does 59 mean?

Communication has been lost between the Master and Follower drives via the SystemBus or CAN communication link. This could be due to incorrect option board parameters or a damaged/disconnected communication cable (optical fibre or CAN). Loss of communication prevents synchronized operation in a master-follower system, leading to operational halts.
