I would pick up one of the kits of used Yaskawas or Mitsubishis over those. He lists peak powers instead of continuos powers. A Yaskawa at 900w will blow those out of the water. Especially with each being driven with a 350w power supply. Cant get 900 watts out of 350.

Yes, funny thing the day I got my Boss IV I saw a 3-axis Yaskawa 750W drive "kit" on Ebay. I checked a few hours later and it was gone :mad:
Have not seen one since !!! Patience is a virtue so I guess I will wait for another one to pop up :cool:

Wow, I didnt know Teco was making servos. Pretty amazing, a 750w motor/drive combo for $630.

They kind of look like a Yaskawa knock off.
