Re: Magnetic encoders? Anybody else having trouble?
We noticed the readout value jumps all over when using the encoders' analog output. This seems to be caused by the slow PWM it uses. Aliasing issues occur when the cRIO samples its analog inputs. I added a simple RC filter and that seems to have sorted it out. I just used a 4.7k in series and a 1uF after that. That seems to have smoothed it out, but as always some tweaking might be necessary depending on your application.
EDIT - For more info, just found the datasheet actually mentions this on page 18... Last edited by AntiSleep : 12-02-2013 at 12:45. |
