Selection validation error
Bosch Rexroth · IndraDrive MPx02
What does F3141 mean?
An error occurred during the validation of a safety-related selection. This implies a problem when selecting or activating a specific safety function or operating mode (e.g., 'Safe Operating Stop', 'Safely Limited Speed'). The selection could be invalid, inconsistent, or fail a self-test, preventing the desired safety mode from being entered securely.
Common Causes
- Attempt to select an invalid or unconfigured safety function
- Inconsistent input signals for safety function selection
- Hardware fault in safety mode selector switches
- Software error in safety selection logic
- Parameter mismatch for selected safety function
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the configured safety function parameters (e.g., S-0-xxxx) in the IndraDrive MPx02 against the machine's safety documentation.
- 2
Inspect the wiring and connection integrity of all external safety inputs (e.g., E-STOP, safety gate contacts, mode selector switches) relevant to the selected safety function.
- 3
Monitor the actual status of the safety inputs and internal safety logic via the drive's diagnostic interface to identify discrepancies or incorrect signal states.
- 4
Check the operational status and output signals of any upstream safety-related components (e.g., safety PLC, safety relay, light curtains) that provide input to the drive's safety chain.
