See page 3-4.
You can run models 1.5Kw and less on single phase.
I have been looking at getting a couple of servo motors for a system I am putting together. I am interested in 1000W version of this series of AC servo drive.

To me the manual is a little ambiguous on the required power. It has single phase AC for control, and three phase for motor drive. However the way it is written makes me think that it might be optional and not required?
If I am wrong here, am I fundamentally looking for something impossible, AC servo on single phase power?

Most AC, BLDC, ECM motors are fed from power of 1ph origin, but as Gerry pointed out, to obtain a smoother, more efficient DC power supply when running the larger versions of motors, 3ph is required or optional.
IOW, The 3ph or BLDC servo power is derived from a DC supply.

Incidentally the BLDC motor is constructed identically to the 3ph version, just the means of commutation and operation is different, the BLDC has only 2 winding's connected at any one time, as opposed to the 3ph three winding connection.
Each can be turned into the other quite easily.

Thank you both for the really helpful replies. And apologies it seems I did not read the manual very well!
