No programming required on supplied drive, plug and play. Seems to have plenty of power for my application. Review: There is a difference between the 2 - There are 2 prices in the listing with no explanation of the difference. I bought the cheaper one not knowing that it is a 2.2k spindle but with a 1.5K VFD. The more expensive one has a 2.2k vfd from what I can tell. It runs fine with the 1.5 so far but I would have liked to know that before buying it, it could have easily been clearly stated in the listing. I was able to download a file from their website with some more useful information on the wiring of the VFD. They had sent me an email after purchase which seemed to suggest not to ground the spindle but I think I just cant understand the translation of what they were trying to say. I studied the wiring diagram quite well before starting and my testing went flawlessly. I screwed the VFD and the spindle to a piece of plywood for testing in case of any motor torque related movement of the spindle. I also tightened a dowel pin into the collet so nothing would go flying. For example the collet nut as you never know if the spindle will start clockwise or counter clockwise the first time or what RPM it will start at. No flying nuts wanted. Its ok to take the nut off and set it aside too but I would be afraid to misplace it. While anyone can wire one of these to some degree and get it working, its worth noting that there are lethal voltages present and exposed after completion of the wiring on the VFD. The VFD should be installed after testing in a suitable enclosure, not on a wall or directly on a machine. Chips, dust, debris, or any object can find the contacts and cause all kinds of unwelcome events that are harmful to nearby people and property. People and objects can also come in contact with something inadvertently that can cause injury or death. Sorry for the safety rant but I have seen so many of these installed in weird places with bad wiring and so on. I saw one installed inside a machine enclosure with the machine! The dimensions for the spindle mounting holes are not all listed anywhere I found so my measurements are- the 7mm diameter holes are 35mm spaced and 95mm side to side. They measure pretty close to those numbers. ## Features - 【Package Include】: ①1 x 2.2KW Square Air Cooled Spindle Motor ②1 x 2.2KW VFD with cable - 【2.2KW Spindle Motor】: ①This is a 220V-2.2KW air-cooled 6A spindle motor come with a ER20 nut and collet.
