Safety command for clearing errors incorrect

What does F3143 mean?

The safety command issued for clearing errors was incorrect or invalid. After a safety fault, a specific, validated command is required to acknowledge and reset the safety system. An incorrect command means the system cannot safely transition out of the fault state, preventing machine restart and maintaining a safe condition.

• Incorrect sequence of error clearing commands
• Invalid data transmitted as an error clearing command
• Communication error preventing correct command reception
• Software bug in the safety controller's error handling
• Hardware fault on the input for error clearing command

Click steps to track your progress.

1. 1

   Verify the safety PLC/controller program logic for the safety command that clears faults, ensuring it matches the Bosch Rexroth IndraDrive MPx02 safety manual specifications for reset.

2. 2

   Inspect the wiring and connections between the safety controller and the IndraDrive MPx02 safety inputs (e.g., STO, SS1 inputs) for integrity, correct polarity, and absence of damage or loose terminals.

3. 3

   Check the safety-related parameters within the IndraDrive MPx02 (e.g., S-0-013x series) to ensure they are correctly configured and consistent with the external safety controller's command structure.

4. 4

   Monitor the status of the safety inputs on the IndraDrive MPx02 using the drive's diagnostic interface or software while attempting to clear the safety fault, comparing observed states to expected states.
