A STOP A command has been initiated, typically as a consequence of another primary safety-related event such as C01701, C01706, C01714, or C01716 (or their C307xx equivalents). This action results in an uncontrolled stop by immediately removing power from the motor.
Click steps to track your progress.
1. Identify and resolve the primary safety fault or alarm (e.g., C01701, C01706) that triggered the STOP A.
2. Verify the status of all safety input signals to the drive (e.g., STO, SS1, SBC) to ensure they are not active or faulted.
3. Check the safety status parameters (e.g., r9756, r9757) in the drive for additional diagnostic information regarding the cause.
4. Ensure that the drive's safety configuration (e.g., p9500 onwards) is correct and matches the application's safety requirements.
5. Perform a safety reset (e.g., through p9699 or cycling specific safety inputs) after the root cause is addressed.
