"The biggest mistake often made with a sensorless vector drive is to allow it to run on the default motor model instead of taking the time to tune the drive to the specific motor that is being used. Many VFDs now come with auto-tune features, but surprisingly few people take advantage of them. The result is performance that is barely better than a scalar drive at a higher cost." quoted from link1) How necessary is this function in our application of motion simulator? Our setup is slight different because we use potentiometer to measure position of the arm lever at the gearbox output. 2) So how do we tune the motor if there is no auto-tuning feature? If I entered manually which parameter is most important? I am sure not many motor provide all the parameters such as stator and rotor inductance, stator and rotor resistance etc. I am looking at many VFD from china, i could not find any that has auto tuning or any MENTIONING of auto tuning.

Is the PA.00 set to 1:Resting self learning an auto tune feature? There is no mentioning of this anywhere else in the pdf manual. Full link to pdf

The PA.00 will most likely try to detect the values of the motor parameters. Not sure if it does that in rest or run or with load or no load... Its a kind of electrical type auto configuration, not really auto tune...
Thanks Thanos
