Re: Big Gecko servo question!!

Mark

I've got nothing against the Gecko. It will handle a bit more than 2hp. And
is a great little performer but with a machine like this I'd use the existing
axis drive amps if they are alive. If not, I'd purchase a set of inexpensive
Copley or equivalent amps and use full PC based servo control with something
like the PPAC boards that Jon E mentioned or the STG or Vigilant, or Studio
Ferraris ISA boards. This solution will require that you figure out what all
the components in the back cabinets

Someone will no doubt jump on the notion that ISA slots are disappearing in
commercial PC's. This may be true but the recent embedded conference in
Chicago proved to me that ISA and RS 232 serial ports and alive and well in
industrial PC's and they will be for a long time yet. This is definitely an
industrial machine.

With all of the space in the computer, electrical, and operator cabinets you
should not have any problem fitting an ISA based solution in there. If you
chose the EMC as your controller, it would be easy to fit several PC's in
there and dedicate one to motion, one to I/O, and one to the graphical and
hard wired control panel.
