Double MST failure shutdown

What does F4001 mean?

The drive detected a simultaneous failure of two Master Status Telegrams (MST). This is a critical communication error indicating a severe disruption in the primary communication link between the master controller and the IndraDrive, leading to a shutdown to ensure safety.

• Complete loss of communication signal on the bus (e.g., PROFIBUS, SERCOS, EtherCAT).
• Faulty communication cable or connectors.
• Problem with the master controller's communication interface.
• Severe electromagnetic interference disrupting bus communication.
• Defective communication interface on the IndraDrive.

Click steps to track your progress.

1. 1

   Inspect the communication cable (e.g., fiber optic, copper) connecting the IndraDrive to the master controller for damage or loose connections.

2. 2

   Verify the status of the master controller's communication interface and bus activity.

3. 3

   Check for external sources of electromagnetic interference that might affect the communication bus.

4. 4

   Power cycle the IndraDrive and the master controller.

5. 5

   If possible, swap the communication cable with a known good one or try connecting to a different port on the master.
