So SZGH are saying that this spindle setup wont work behind an invertor / filter. Of course, it might, but not surprised as without testing / knowing, they put their hardware and reliability at risk.

So, anyone want to buy a 7.5KW 380 3 Phase Driver, Spindle Servo Motor, cables and braking resistor? The cost to me was $USD 990, plus a bit of tax and sadly the shipment was expensive due to the weight of the motor (60 ish KG). Let me know if interested. Ill possibly stick it up for sale on a few other places too.
