Hi,
good news, you won't be dissapointed....they really are light years ahead of any stepper.
I personally use two MB02's from Homann Designs in Australia. As I live in New Zealand its near enough to be
local....after all its only 2500 km away......no more that a brisk swim for a Kiwi...LOL.
A cheap and effective breakout board is the C25, at only $30.00. It has two ports developed (34 IO's).
Note however they are TTL level, that is 5V. The inputs to the Delta drivers are 24V, being the norm in industrial
equipment. Thus you will need to add a resistor and a transistor/mosfet to effect the level translation. I can help
with cicuit diagrams if you need.
Another alternative is to use a MB3 breakout board from CNCRoom at $180. It has all three ports developed (51 IO's)
and its outputs are 24V tolerant. You are (somewhat) constrained to the architecture that the manufacturer has provided
but is a well balanced mix of inputs and outputs and a mix of differential and single ended. It require but one 24V power
supply and supplies (on board) 5V to the ESS.
Modern AC servos are quite complex to set up and a vast array of parameters that you need to consider.
In most cases the manufacturer offers a way to plug the drive into a PC so that you can program the drive using
the manufacturesrs software, and is highly reccommended. You can program a Delta drive by button pushing
(four buttons) on the drive itself, a bit like programming a watch. It will drive you up the wall!!. Get the required
communication cable and use the software. The tuning aids alone make it worthwhile. I promise you....you will
be amazed by the flexibility and control that can be achieved with a modern AC servo.
Delta drives are programmed using an IEEE1390 plug, which can be wired in two ways, one of which can damage the
drive. I elected therefore to buy a genuine Delta accessory cable, of course you need only one cable and can program
many drives with it.

is the correct way to get the best from your servos.
