Hi was wondering if anyone can confirm that my logic is good before I power up for the first time? I just received a new StepperOnline T6 series 1kw servo drive and motor kit. In the video they show someone one powering it using a 24v power supply for testing but the manual says its rated for 220v single phase. What I'm hoping what I can do is power it directly from a 120v wall outlet. Is this ok to do this and what's the draw back of using 120v instead of the rated 220v? Also does it matter what the order is on the neutral an hot leads go on the drive? In the manual all it shows is an L1 and L2 then on the bottom is a ground? Thanks

Hi,
I use Delta servos which are very similar.

You hook the incoming AC to L₁ and L₂. The polarity does not matter.

My Delta drives and I suspect your also will require a line level AC supply that powers the DC signalling side of the servo, in which case L₁ and L₂ will be paralleled
to these inputs.

My line level AC here in New Zealand is 240VAC and I can hook direct to my drives.....they are rated to 255VAC input. I rather suspect if I tried 120VAC they would still work but I think they would not have the top
speed that I would expect.

Certainly do not think there is any harm in trying 120VAC. If it does not work or you get Low Voltage alarms then you'll have to supply 220VAC...end of story.

Ok thanks, I tried 120v and the drive did not work. Went and built a sketchy dual circuit outlet adapter to get 220v and it started rite up. Left the ground disconnected though because I don't have qualifications of an electrician and 220v scares me that I wont ever have the chance to explain what making a mistake is like with it. Anyways these drives only work when powered to specification. Thanks
