Fast linear and rotary motion done cheap.

Fast linear and rotary motion done cheap.

(OP)
I have a company that turns a 115V dc motor off and on while reading the feedback from a micro0pulse sensor (balluff.)  They calculate the position and using a brake on the motor they try to sto0p this wo within .005".  ROFL, I know.  They have to slow the system down just to get it within .025 to .015 depending on up or down motion.  I need to locate an inexpensive unit that I can blow a position value to via rs232.  Should be closed loop of some type.  Using a Fx2N plc as the main machine controller.  The load is 100lbs, must move 5"/second and the unit should have 6 to 8 inches of travel.  Models should be available for u0p to 300 lbs.  )Power source is 220vac single phase 3wire.  Will also need a rotary setup to talk on the same netowrk, so 232 to 422 or 485 should be looked at.  The rotary unit only has a 20lb reduced load and will not need to be too beefy.  

I'd like a single controller card for both axis so I don't have to convert the 232.

I have several solutions but I am used to very robust powerful machines in which money was not an issue.  On these machines, a product line, it has become a very important issue.  I do not know what is available on such a low price tag.

Is it a one off or can you take the cost to develop custom units?

They will be making over 100 units per year.
