14.5 Average sin²+cos²
Calculated average value to the normal distribution of the encoder track signals from the
(sin²+cos²) monitoring. The value corresponds to the radius, thus the square root of
(sin²+cos²) and is displayed in the resolution of the A/D converter (2048 is equivalent to
1.0).
14.6 Max sin²+cos² variance
Error threshold for the variance monitoring of the (sin²+cos²) value. If the variance ex-
ceeds this threshold an error message is set off.
14.7 Variance quality factor
This parameter indicates the quality of the calculated signal variance (Z14.4–) of the
(sin²+cos²) value of the encoder signals. The variance is calculated using the least errors
squared method. The sum of all errors squared is a measure of the quality of the calcu
-
lated variance and should be as small as possible.
14.8 Absolute range of fluctuation
The absolute range of fluctuation of the (sin²+cos²) measured value in percent.
14.9 Tolerance
14.10 Max error count amplitude
Set value for (sin²+cos²) amplitude monitoring of the encoder signals. At activated moni-
toring an error message is generated corresponding to the preset numbers of exceedings
or under-runs of monitoring threshold.
14.11 Error count lower limit
Display of how often the minimum threshold (sin²+cos²) has been under-run.
