Error during phase progression

What does F4004 mean?

The communication between the IndraDrive and its master controller failed to progress to the next expected communication phase. This indicates a stall or failure in advancing through the required communication states (e.g., from phase 0 to 1, or 1 to 2), preventing operational mode.

• Master controller not issuing the correct phase progression commands.
• Drive not acknowledging phase change requests.
• Communication bus issues (e.g., noise, cable damage) preventing reliable phase negotiation.
• Incorrect communication parameters in either the master or slave.

Click steps to track your progress.

1. 1

   Verify the configuration of the master controller to ensure it is correctly managing the communication phase progression.

2. 2

   Inspect the communication cable and connections for any physical damage or loose contacts.

3. 3

   Check for any errors or warnings on the master controller that might indicate communication issues.

4. 4

   Review the IndraDrive's communication parameters (e.g., bus address, baud rate) to ensure they are correct.

5. 5

   If applicable, use a bus analyzer tool to monitor communication traffic and identify the exact point of failure in phase progression.
