Safety command for system halt incorrect

What does F3151 mean?

This non-fatal safety error indicates that the command received by the IndraDrive MPx02 to initiate a safety-related system halt is incorrect or invalid. This implies a failure in the safe shutdown process, which is critical for machine safety.

• Incorrect sequence or timing of the safety halt command from the master controller or safety PLC.
• Mismatch between the expected and received safety halt command (e.g., wrong bit pattern or value).
• Communication error preventing the correct safety halt command from reaching the IndraDrive MPx02.
• Incorrect parameterization of the safety halt logic.
• Failure of internal safety logic to correctly process the halt command.

Click steps to track your progress.

1. 1

   Verify the exact sequence, timing, and value of the safety system halt command being sent by the master controller or safety PLC.

2. 2

   Check safety parameters in the IndraDrive MPx02 related to safety halt logic and response.

3. 3

   Inspect the communication link between the master controller and the IndraDrive MPx02 for errors.

4. 4

   Ensure that any external safety devices triggering the halt command are functioning correctly.

5. 5

   If the error persists despite correct external commands, a power cycle of the IndraDrive MPx02 may be necessary to clear internal logic states.
