: Once the identification is complete, perform a RAM to ROM copy to ensure the new parameters are saved permanently to the drive's non-volatile memory. Related Faults to Check

If the code persists or is accompanied by other errors, consider these related Siemens drive faults: : Motor blocked or speed controller at its limits.

When a sensor or actuator cable is shorted to ground or to 24V, the I/O module may detect an overcurrent condition. Some modules go into "fault" state and report via diagnostic interrupt 0A7991.

:

, the drive has been commanded to perform this "identification" routine (often called an auto-tune) but hasn't completed it yet. While this alarm is active, the drive typically cannot be started

: Set this to 0 to remove the requirement for motor details entirely during initial testing. Finalize Configuration (RAM to ROM)
