November 2014 Software description 97
Example: ECN rotary encoder
If the deviation span is extremely high (red display), check the setting of the incremental
counting direction .
9 Warning "EnDat non-compliant datum shift"
10 Permitted accuracy deviations [LSB] at defined speed ranges [rpm]
11 Rotational speed at deviation; if green lines are shown, this range is not supported.
12 Adapt the counting direction of the incremental counter, if the counting direction of a
programmable SSI rotary encoder was reprogrammed.
