Linear Encoder Display Using Quadrature Decoding

Post by slisk »

Is there anyway to get a simple continuous count with quadrature decoding without a revolution count limit or angular display? I'm using linear encoders to measure mechanical properties and the rotary encoder settings in the existing decoder are not usable for that.

If it's not possible, is there any hope of a future release with that feature?

Hi Slisk,

Sorry for the late response. If you haven't already resolved this then the answer is as follows:

Would the following be an example of what you are looking for, (i.e. summing the impulses, in the displayed data below, where the direction change is accounted for, to give total displacement):

...or were you also looking for Speed, or anything else?
If you can let me know, then I'll submit an enhancement request to our development team.

Unfortunately the created data file uses Math functions that that don't work well together, and can't be processed further (e.g. integrated) so, I can't offer you a workaround in the meantime.

Regards,

Thanks for giving this attention, I do still need help with this.

I need to measure each transition on both A and B. I notice towards the end where B goes low then high, without a transition on A, there is no response. That would still reflect physical movement on an encoder and I would need to capture that for maximum resolution.
