This particular driver (linked below) connects directly to AC so it's 240vAC. It has the PSU built in unlike the DM 542T drivers I have which utilize a separate PSU that supplies 42.5 volts.
Just to be clear that you are using the 3 phase driver that is supplied by 230v ac. I so that is fine.

As a lot of steppers are two phase. I take it your stepper is actually 3 phase.

What controller are you using to drive it ?
