: This is an alarm, not a fault. It indicates that the drive is currently performing a "Motor Data Identification" (motor ID run) to measure the motor's electrical characteristics.
This alarm is technically a safety and performance feature. It ensures the drive accurately measures the motor's electrical characteristics (like resistance and inductance) to optimize performance. However, users often find it intrusive when it appears unexpectedly after a power cycle or during site testing where the intended motor isn't yet connected. siemens fault 0a7991
If you cannot run the identification (e.g., the motor is connected to a load that cannot move), set manually. Permanent Save : : This is an alarm, not a fault
