very slow to position a servo motor with 8i20

Question regarding 8i20.

If you have 220VAC servo motors, what DC level is needed to power this combination optimally?

Cheers

DC needed would equal the peak AC voltage (so something like 311VDC for 220VAC)

Note that this voltage is just what you get with a 220VAC line operated capacitor input power supply

OK, so locally we have 230V that x1.417 gives about 326 so it should be within motor margins.
