00b 2 01b 4 10b 8 11b 16 7.3.6.1.7 Ripple Count Threshold Denoted by RC_THR, this parameter represents the threshold setting for the total number of ripple counts vs the total number of ripple counts estimated by the ripple counting algorithm based on the expected time of motor actuation....
Although measuring unloaded motor RPMs is the main goal of this setup, the results from it were verified using a handheld laser tachometer when a prop was attached so I'm pretty confident it provides reasonably accurate results. A few additional details are noted in this post, more can ...
The encoder used was a Monarch Instrument ACT 3 Tachometer/Totalizer/Ratemeter (Amherst, NH, USA). This encoder was configured to output an analog voltage proportional to the motor speed. The offset value and full scale speed values of the encoder were programmed to values close to the motor...
