Double MDT failure shutdown
Indramat · Indradrive
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.
Common Causes
- 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).
Repair Steps & Checklist
Click steps to track your progress.
- 1
Inspect the communication cable (e.g., fiber optic, copper) connecting the IndraDrive to the master controller for damage or loose connections.
- 2
Verify the status of the master controller's communication interface and bus activity.
- 3
Check for external sources of electromagnetic interference that might affect the communication bus.
- 4
Verify the communication parameters (e.g., baud rate, address) are correctly configured in both the IndraDrive and the master controller.
- 5
If the fault persists, the IndraDrive's communication interface may be defective.
