View Full Version : Panasonic 3 phase driver running on 1 phase?

10-05-2012, 12:28 PM

I have some panasonic servo drivers model number MSDA043A1A

I would like to wire them using a single phase supply, but from the model number I can tell these are meant for 3 phase supply. Panasonic tell me it is possible to use a single phase supply but will not tell me how to. I don't have the knowledge to work it out so I was interested to know if anyone has done this before and how do I go about it.

I am in the UK and I have a 230-240v single phase supply.

My servo has the connections L1, L2, L3 and ground.

Many thanks

Try this link and see if it is the correct manual for the drive amp you have. http://industrial.panasonic.com/ww/i_e/25000/minas_a_e/minas_a_e.pdf

Page 22 gives you the connection options.

You could have a quick look inside the drive and see what L1,2,3 are connected to. If it's just a 3-phase rectifier then connecting single phase to any two of L1,2,3 will work, although you may have to de-rate it. That's how most VFDs are done.
