The actual upper limit for the measurement length to be entered in steps is dependent
on the measuring system version and can be calculated with the formula below. As
the value "0" is already counted as a step, the end value = measurement length in
steps - 1.
Total measuring range = Steps per revolution * Number of revolutions
Formula 2: General - Scaling parameters
To calculate, the parameters
steps/rev.
and
the number of revolutions
can be read
on the measuring system nameplate.

8.4.3.29.2 Attribute 102/103, Revolution Numerator/Denominator
Together, these two parameters
Number of Revolutions Numerator
and
Number of Revolutions Denominator
define the
Number of revolutions
before the measuring system restarts at zero.
As decimal numbers are not always finite (as is e.g. 3.4), but they may have an infinite
number of digits after the decimal point (e.g. 3.43535355358774...) the number of
revolutions is entered as a fraction.
