Panasonic 3 phase driver running on 1 phase?
Hi,
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
Gav

so basically a 1 phase input should run a 10 amp motor with 15 amp rated driver?

If the encoder plays niece that can work, if you have a phase lose alarm there is a way around that as well.

Possibly, but you need a big enough single phase supply and cable gauge size. The current draw may make the cable get hot or even fry supply wire insulation.
3^.5 times bigger.

what the relation between the encoder and power input to the driver? I'm not getting that. Please explain

Some Servo Motor / Encoder has to recognize the drive they are being connected too, so if the motor size does not match the Servo Drive, they will not work, this is with most quality Servo Drives Motor combo, in your case it should work,
As for cable the size is related to the Amps being used only so if the max amps is 10A, the correct wire size would be rated at 12.5A this is what code would require.
