No, there is not an automatic function to do this. It would be very hard to devise a generalized scheme for this (e.g. when does it start, stop, and clear the calculations). As an analogy, I find the "average gas mileage" reading on my car to be useless, because I have no idea over what time span it operates.

 

Also, very few people request this functionality, so even the overhead to decide whether or not to calculate this on an every-servo-cycle basis would not be worth it.

I agree with your comments, and would not have purposely created such a signal either, but thought that maybe there is an approximate signal that was created for some other purpose that I was not aware of.

 

It turns out that what I really need is a band pass filter on the following error signal whose center frequency is variable, and I only need to have this signal occassionally, so I will just write a PLC that implements a digital IIR filter.

 

Thank you for taking the time to respond.
