Spindle motors: Elte TMPE4 14/2, 12000 RPM, 3,7 kW http://www.eltesrl.com/index.php?option=com_content&view=article&id=26&Itemid=48&lang=en VFD: Teco E510-415-H3F https://www.inverterdrive.com/file/Teco-E510-Manual-EN-v2 Yes, these motors are asynchronous motors. I tried tweaking VFD parameters, but without any luck. The same settings work for "normal" 0,55 kW motor, those spindles work fine with 2kW VFD I have on my router, but together the large VFD and those spindles (even when one spindle is attached at a time) do not work. I will try to find some inductors to try Jon's suggestion. I would appreciate any help in finding them (seller within EU is preferred).
