Abstract: Detection of mechanical coupling slippage in rotary encoder systems is provided where position data samples are obtained from a rotary encoder coupled to rotating element and angular acceleration data is determined based on the position data samples. At least two acceleration peaks are detected in the angular acceleration data, including at least one negative acceleration peak and at least one positive acceleration peak. Slippage occurrence of the mechanical coupling are detected when an interval between a negative acceleration peak and a positive acceleration peak of the at least two acceleration peaks is less than a first time period. If at least a threshold number of slippage occurrences are detected within a second time period, a mechanical coupling error signal is generated.
