Re: [CAD_CAM_EDM_DRO] Re: +/- 10 V To Step/Dir Converter Circuit

Hi All,

I intend to use this circuit between a CNC control
which outputs +/-10 V for servo drives and Rutex or
Gecko Servo Drives i.e this circuit will take 0 to
+/-10V and convert this voltage to Step and Dir for
Rutex or Gecko input.
