Actual position value validation error

What does F7041 mean?

This safety technology error indicates an inconsistency or corruption detected during the validation of actual position values for safety functions on the IndraDrive MPx02. This means the safety system cannot reliably determine the motor's current position, compromising safe motion monitoring and leading to a safety stop.

• Mismatch between redundant position feedback signals (e.g., primary and secondary encoders).
• Encoder fault or damage leading to incorrect or noisy position feedback.
• Interference or noise on encoder signal lines.
• Incorrect scaling or parameterization of encoder feedback for safety functions.
• Mechanical slippage between the motor and the load, or between the encoder and the motor/load.

Click steps to track your progress.

1. 1

   Compare the actual position values from both primary and secondary encoder systems (if dual encoder system is used) to identify the discrepancy.

2. 2

   Inspect encoder wiring for proper shielding, secure connections, and damage. Check for electromagnetic interference near encoder cables.

3. 3

   Verify encoder parameters in the IndraDrive MPx02 (e.g., S-0-0192 'Encoder 1 resolution', S-0-0193 'Encoder 2 resolution') for correct scaling and resolution.

4. 4

   Perform an encoder test or recalibration to ensure accurate position measurement.

5. 5

   Check for any mechanical issues causing slippage, such as loose couplings, worn belts, or binding mechanics, that could lead to position discrepancies.
