Thank you for your reply.
If you get the Machdrives please let us know if they are easy to tune.The Tuna
software looks easy to use and appears to be full featured but you can never
tell till you use it.If you do order, order soon. International shipping takes
several weeks.I asked if they wanted me to be a stocking US dealer. They said
no.
I went with the 160 volt drives as that gives me some voltage head room to
prevent shutdown on a voltage surge.

Hi Dale,
Thanks for the info. Those might well serve me in case of using the
original DC servos the machine has.
