text: <s>[INST] Extracting Motor Parameters from the PowerFlex700 Drive Hi,Correct me if I am wrong. As per my understanding the auto tuning process of the drive generates a machine model (stator resistance, rotor resistance, stator and rotor inductances, leakage inductance, motor inertia etc) within the drive memory. So my questions are: 1) If i keep the motor coupled to the load during auto tuning (rotate tune), is it okay??2) Is it possible by any ways to get the motor parameters that were determined by the drive? I mean is it possible to read the stator resistance, rotor resistance etc. from the drive As always thanks and regards Jai [/INST] The autotune process initiated by P61 determines values for IR Voltage Drop, Ixo Voltage Drop, and Flux Current Reference. These are parameters 62, 63, and 64. This autotune is to be done if running the drive in one of the vector modes are selected by P53 after setting the correct values for P40 through P49. The autotune done by P61 can be done 3 ways, Calculate, Static, or Rotate. Rotate tune must be done uncoupled or the tune will not be correct. If you cannot uncouple the load then perform a static tune. The inertia of the system is found by running the autotune in P67. This tune is to be done coupled to the load if this can be done safely. The inertia autotune ramps up very quickly at the torque specified in P66 and monitors the time it takes to get to full speed. As for getting the resistances and inductances of the motor, there is no way to get this information from the drive. \\n </s>
