"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 link
1) 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.
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...
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

tronicgr: dureiken Hi, Open a thread and I'll try my best to help. A little busy with Kickstarter details at the moment but I'll see what I can do.

fimmy: How's the firmware going?

tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
