QEP Speed calculator block settings ?

Swapnil Bongale_21857

I am using teknic 2310P-LN_04K motor for FOC sensored drive...I am stucked between how to choose values in the block setting of "QEP Speed Calculator" block...

Can you please describe how to choose these values...what are guidelines for that...is there any formula for that ?

If you click the help button on the block, you should get this:

Base Electrical Frequency - Indicates the maximum rotational speed of the electrical field between poles.

Control Sampling Rate - Indicates sampling rate of the control running on the target and hence the rate at which the quadrature encoder will be sampled

Low Pass Cutoff - A low-pass filter is applied to the successive differencing used to determine speed from successive QEP samples. Speed changes above the cut-off frequency will be attenuated.
