Device removed

Vacon · NXS NXP

What does 39 mean?

An option board has been removed from its slot, making the device unavailable to the drive. This indicates a configuration change where a previously installed board is no longer present. The drive needs to acknowledge this change to clear the fault status.

Common Causes

  • Option board physically dislodged from its slot due to vibration or improper seating during installation.
  • Accidental removal of an option board while the drive was powered off but configuration retained.
  • Incorrect handling during maintenance, leading to an option board not being reinstalled correctly.
  • Software configuration (e.g., parameter P7-01) indicating a board present that has been physically removed.

  2. 2

    Open the drive enclosure and inspect all option board slots for the presence of a board.

  3. 3

    If an option board is missing, reinstall the correct board into its designated slot.

  4. 4

    Verify the secure seating of the option board by checking retaining clips or screws.

  5. 5

    Power up the drive and confirm the fault clears. If not, check parameter P7-01 for board configuration.
