Hi,
if you use Delta servos at my recommendation then you don't need power supplies for the servo drives, they
are 230VAC input.
The Delta servo drive has a 24V output, limited to only 500mA, which is intended for use with signalling between
the breakout board and the drive.
If you use a simple breakout board like a C25 then you will need a 5V power supply for the breakout board and the ESS.
A C25 (or even sipmler C10's) will require some extra circuitry in the form of a level translator transistor/mosfet.
The advantage of the simpler boards is that you have the greatest flexibility but comes at the expense of you having
to provide the little bits of circiutry required.
If you use a more sophisticated MB3 from CNCRoom, then one independant 24VDC power supply will power both the
breakout board and the breakout board will break down 24V to 5V for the ESS.
The MB3 has differential outputs, about 12 of them, especially for high signalling rate to servo drives
which are perfect for you. No extra circuitry required. The MB3 has gained a good reputation beacause it has been well
thought out so that a user requires very little or no electronic skills to achieve a workable solution. That comes at the
expense of flexibility. None the less the MB3 has gained a good following.
If you want to represent to your professor that the 'lowest risk' solution is an MB3. If you need to save pennies then
the C25 is perfectly workable but requires some electronic skill from you.
