      Hanermo You ROCK. Have to go away for 4 days but will be straight onto it
      ASAP.



      Thankyou thankyou



      Kind Regards

      (I dont have a C23- but the setup is the same as for a c6 board. Mine
      are connected to a lathe spindle motor control, but the procedure is the
      same for a mill. I get about +/- 1 rpm variation in steady state speed
      ie non-cutting).

      Ok .. to start with, lets ignore the direction.
      Pin 14, on the C23 bob, is analog out.
      So, in mach

      Ports n pins/Motor outputs
      At the bottom, for spindle, check the right step/ dir pins for your setup
      the step pin is pin 14 (port 1 of the SS I think).
      the dir - use any free pin with relay (set this up later).
      Save and exit mach. Restart mach (just in case).

      So, for the analog out, between connectors 1 and 2, on the C23, you will
      get a voltage that is proportional to the commanded speed of your spindle.
      This is next to the trim pot, that adjusts your voltage.

      Connect a volt meter to pins 1,2 on the c23, meter on dc 12 V range
      (without vfd).
      set the speed to say 1000 - in mdi in mach with S1000 (assumes mm/sec)
      (Voltage should be zero - spindle is still off).

      Put on the spindle, from the screen.
      The voltage between these pins should now be near 10 v.
      Put your spindle speed, in mach, to your max real speed.
      Assume max spindle speed is 3400 (Bp M-head ;) for example.
      S3400
      Now adjust the trim voltage on the C23, the R37, so that its output is
      your vfd max, 10 V.

      Now connect the pins 1,2 to your vfd.
      Mach can now control the speed of your vfd -> spindle !

      Then put a relay, or use the relay on the C23, to the dir pin on your vfd.
      If using C23 mechanical relay - use pin 16.

      Ports n pins/Motor outputs
      At the bottom, for spindle, check the right step/ dir pins for your setup.
      Step is already set up.
      the dir pin is now pin 16 (port 1 of the SS I think).
      Now, you should be able to change the direction of the spindle, cw/ccw,
      from the screen or with mdi.

      Hope this helps.
