Double MDT failure shutdown

What does F4002 mean?

The drive detected a simultaneous failure of two Master Data Telegrams (MDT). This is a critical communication error indicating a severe disruption in the primary communication link where the master controller fails to receive expected data from the IndraDrive, leading to a shutdown.

• Complete loss of communication signal on the bus.
• Faulty communication cable or connectors.
• Problem with the IndraDrive's communication interface failing to send data.
• Severe electromagnetic interference disrupting bus communication.
• Incorrect bus configuration (e.g., wrong baud rate, address).

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

   Verify the communication parameters (e.g., baud rate, address) are correctly configured in both the IndraDrive and the master controller.

5. 5

   If the fault persists, the IndraDrive's communication interface may be defective.
