Refer. missing when selecting safety related end pos.

What does F3111 mean?

This non-fatal safety technology error indicates that a safety-related reference or datum is missing when attempting to select a safety-related end position. This prevents the drive from reliably establishing its safe operating limits, impacting safety functions like Safe Limited Position (SLP).

• Safety reference point for the axis has not been set or is corrupted.
• Encoder fault preventing accurate position feedback for safety functions.
• Incorrect configuration of safety parameters related to reference positions (e.g., S-0-0193, S-0-0194).
• Problem with the safety encoder or its connection to the IndraDrive MPx02.

Click steps to track your progress.

1. 1

   Verify that the safety reference point for the axis has been correctly established and stored according to the machine's commissioning procedure.

2. 2

   Check the primary and secondary encoder feedback signals for integrity and proper operation.

3. 3

   Review safety parameters in the IndraDrive MPx02, specifically those defining reference positions and safety limits, to ensure correct configuration.

4. 4

   Inspect the wiring and connections of the safety encoder for damage, loose terminals, or improper shielding.

5. 5

   If an external safety PLC is used, verify its programming and communication with the IndraDrive MPx02 regarding reference position management.
