A method for operating an encoder system and an encoder system

摘要

The present invention relates to a method for operating an encoder system characterized by the steps of:
- determining a value of a first encoder operational variable;
- weighting said value in dependence of at least one other operational variable of the encoder, influencing the lifetime of the encoder;
- providing a reference value of total encoder lifetime in respect of said first encoder operational variable;
- calculating the remaining lifetime of the encoder in respect of the first operational variable based on the weighted value and the reference value of total encoder lifetime wherein,
weighting values are predetermined for intervals of the operational variable influencing the lifetime of the encoder whereby, the weighting value for the operational variable in question corresponds to the interval in which a sampled value of the operational variable falls within. The invention also relates to an encoder system for performing the disclosed method.
