I am facing probelm of excessive vibration with one of our AC motors. Upon investigation we found that motor is drawing unequal current. i.e Red=171A at 377V, Yellow=298A at 389V, Blue=306A at 382 V.The motor is driven by a simovert master drive VC(CUVC). The motor control is closed loop with digital techometer. I wanted to know if automatic parameterization via P115=3 would help?Also if anyone has done auto perameterization can you please tell me wether following the attached procedure is adequate or their are certain ambiguities during and after the procedure that we should look out for? Further I tried to change the parameter P60 to 5 while the inverter (simovert master drive) was in ready state i.e r001=011, but I wasnt able to do so untill I switched off its main dc supply and then changed the parameter P60 to 5. Is there any other way to start the auto parameterization procedure?
