Repeatability

Repeatability describes the precision of multiple moves to the same point within a short time period (from a few milliseconds up to five minutes).

During repeated moves to a position within a short time period (from a few milliseconds up to five minutes), deviations will occur between the repetitions. For a warmed-up system (warm-up: 30 minutes) with steady ambient temperature and operational conditions, the imprecision's standard deviation ( RMS ) lies within the specified range. Here, it is assumed that dither averages out.

Systems with digital encoders have clearly superior repeatability.
