F01697

Test stop for motion monitoring is required

Siemens · SINAMICS G120

What does F01697 mean?

The set time (p9559) for performing the forced checking procedure (test stop) of the extended functions has been exceeded. This indicates a required safety test is overdue, compromising safety integrity if not performed and potentially leading to a fault state.

Common Causes

  • The scheduled test stop for Safe Motion monitoring functions (e.g., SSM, SDI) has not been performed within the interval defined by p9559.
  • The required test stop procedure was initiated but failed to complete successfully, perhaps due to an external condition.
  • Parameter p9559, which defines the test interval, is set too short for the application's operational rhythm or maintenance schedule.
  • An external safety PLC or higher-level controller has failed to trigger the required motion monitoring test.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    1. Initiate the forced checking procedure (test stop) for the extended safety functions as per the safety manual (e.g., by activating specific test inputs).

  2. 2

    2. Monitor the relevant safety status bits (e.g., r9756) to confirm the successful completion of the motion monitoring test stop.

  3. 3

    3. Review parameter p9559 to ensure the test interval is appropriate for the application and maintenance schedule, adjusting it if needed.

  4. 4

    4. Verify the external safety circuit or PLC logic responsible for triggering the motion monitoring test stop is functioning correctly.

  5. 5

    5. Document the completion of the safety test stop in the maintenance logbook.
