Abstract: Embodiments of the present invention provide a motor-driven mechanical system with a detection system to measure properties of a back channel and derive oscillatory characteristics of the mechanical system. Uses of the detection system may include calculating the resonant frequency of the mechanical system and a threshold drive D TH required to move the mechanical system from the starting mechanical stop position. System manufacturers often do not know the resonant frequency and D TH of their mechanical systems precisely. Therefore, the calculation of the specific mechanical system's resonant frequency and D TH rather than depending on the manufacturer's expected values improves precision in the mechanical system use. The backchannel calculations may be used either to replace or to improve corresponding pre-programmed values.
