[QUOTE="Sidewinder, post: 471447, member: 9512"] My MFT has phase rotation and I also have a separate phase rotation meter. It's normally the installation guys on CNC machinery that get hung up about it, especially the cheap ones, because they don't fit hose rotation detection to them, so it has to be right, or it screws them up. The better drives either don't care, or they tell you that it's wrong. With AC permag servo's it doesn't really matter as they take the 3ph and make DC out of it to chop it up again as a PWM waveform, and the motor rotation is dependent upon which order they fire the output stages anyway, so that's down to the drive control.
