Safety related holding system: system error

What does F3122 mean?

A general system error has occurred within the safety-related holding system. This system is responsible for safely holding the motor or axis in position, often through mechanical brakes. This fault indicates a critical failure in the holding mechanism's overall operation, requiring immediate attention to prevent unintended motion or dropping of loads.

• Failure of the motor holding brake mechanism
• Brake control circuit malfunction
• Feedback sensor for brake status is defective
• Internal safety module error affecting holding system control
• Loss of power to the holding brake

Click steps to track your progress.

1. 1

   Inspect motor and brake control cables for damage, loose connections, and proper shielding between the drive and the motor/brake.

2. 2

   Verify drive parameters related to the safety-related holding system (e.g., brake control, monitoring settings) for correct configuration as per machine documentation.

3. 3

   Measure the resistance of the motor brake coil at the drive's output terminals (with power off and locked out) and compare to the motor's technical specifications.
