The Samsung servos need a Samsung drive. Or better said, you could not hook other servo motor to a brand drive. As it auto detects motors and will give " Faulty" all of the time. Samsung motors have 9 wires to encoder, some 11. The one on link is with 9 wires.

The only way you could make a similar motor work is Universal servo drive like Granite Devices.

And yes, that motors are good price and good ones, but you can check the Samsung PDF manual link i send you earlier and see that for yourself. But remember what i told you about the servo cables. Dont make decisions without knowing what will cost you when you include them. The good thing is these motors are in Europe. You could buy the drives for around 130 each, used.

DMM are out of question in Europe. Going that way is better to buy Chinese drives or the second hand Samsung. I have pondered over that many times last years and every time money and price prevails.
