Rutex R2030 Servo Drive cards x 3 with R2110 Motherboard and chassis plate.

Cards are dated 2005 and were used to setup a Hurco KMB1 Mill. Unfortunately the  Mill had other issues and then I lost the space I had it in so the cards were removed and have been sat in a box ever since.

Were in full working order when removed from the machine with only a few hours use (literally just setting up the axis to get it moving).

Suitable for up to 100V/20A. Unfortuntately I dont have any way of testing them anymore so I have listed them as Part/not working (although I'm 99% sure they will work withouyt problems).

Software and specs available at: http://www.rutex.com/us/index.php?productID=125

These are currently list at over £450 so grab a bargain and get that CNC moving :)



  • Servo Motor Drives for brush-less servo motors up to 100V/20A.
  • Step&Dir or SPI (Serial Peripheral Interface) motion command
  • Advanced SPI motion with up to 255 points 32-bit fractional interpolation and 8 x 32-bit FIFO buffer.
  • Up to 7 axes can be controlled from single printer port via SPI at theoretical speed up to 80Mpps.
  • SPI DLL (XP/W2K) available for software developers.
  • Build-in true real time 32-bit DRO.
  • Build-in safe Limit Switches input.
  • Encoder "tap" output - raw A/B/I and decoded clock Up/Down.
  • Output for optional external braking resistor.
  • Encoder Index offset counter.
  • Enhanced 32-bit PID filter - quieter, up to 40% faster setting time than standard PID.
  • Following Error Trip adjustable from +/- 2 to +/-32766.
