encoder conversion

已解决!
转到解答

I have this encoder factor and I'm trying to figure out how to convert it to real world units for Velocity and Acceleration.

 

1.0 mm / 34,304 counts

 

How do I get the following :

 

1.0 mm/s (velocity) = ????

 

1.0 mm/s^2 (acceleration) = ????

 

 

thanks

You can do it based on frequency.

 

Or you can just get the counts once a second.  From there, it is really simple math: counts/34304

To calculate velocity, first capture some number of points. As Tim pointed out distance is counts/34304.

Velocity is that value (distance) divided by the time it took to collect the counts.

Acceleration is the differences in velocity between consecutive data points divided by the difference in time between the two data points. dV/dT
