Follower communication

Vacon · NXS NXP Drive

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.

Complete Troubleshooting Guide

  1. 1

    Verify the option board parameters on both master and follower drives to ensure correct communication settings.

  2. 2

    Inspect the physical optical fibre or CAN communication cable for damage, breaks, or loose connections.

  3. 3

    Ensure proper termination of the communication bus if applicable.
