Todd,
I am glad you asked this question, I am in the beginning stages of
retrofitting my Cincinatti Arrow 500 VMC to linuxCNC and the 130mm
industrial AC servos and drives from DMM are one of the options I am
considering right now. They sure look good from the specs and I have heard
and seen a lot of good results from people who have used their smaller
sized servos and drives on smaller machinery. These are newer products
they are selling altho speaking with them over the phone I got excellent
information and help with wiring instructions in a relatively long
conversation. I also found that their new drives are somewhat easier to
wire up than the majority of the ones I am investigating since the inputs
and outputs for control are on a db9 connector instead of the 25 pin
style. I hate wiring and soldering and found that it is entirely possible
to use a ready made db9 cable and plug it into the drive and then open up
the other end to adapt it to the mesa cards I am using. I will be
watching this thread here and hope to get some information that will help
both of us. The motors use absolute encoders which I thought was a
difficult setup system but after talking to them the encoders are adapted
specifically to their drives and controlling the drives can be done either
analog 0-10v, step and direction or another way I cannot remember. So the
encoder is not an issue as long as you intend to use their drives. Also I
assumed their motors and drives were chinese but when I asked where they
were made over the phone he told me they were made in Canada, dunno how
accurate that is but that is what they said and I was kinda surprised by
their answer. It is possible he meant they were designed in Canada but he
actually said they were built there. Peace
Pete
