8.4.3.29 TR-Scaling parameters
(≤ 64 bit)
To use “Attribute 101, Total Measuring Range” and “Attribute 102/103, Revolution
Numerator/Denominator
” the “Attribute 105, TR-Parameter in use (scaling)” must be
set to “1”.
Danger of personal injury and damage to property exists if the measuring
system is restarted after positioning in the de-energized state by shifting
of the zero point!
If the number of revolutions is not an exponent of 2 or is >4096, it can occur, if
more than 512 revolutions are made in the de-energized state, that the zero
point of the multi-turn measuring system is lost!
Ensure that the quotient of
Revolutions Numerator / Revolutions
Denominator
for a multi-turn measuring system is an exponent of 2
of the group 2

Ensure that every positioning in the de-energized state for a multi-turn
measuring system is within 512 revolutions.
The scaling parameters can be used to change the physical resolution of the
measuring system. The measuring system supports the gearbox function for round
axes.
This means that the
Steps per revolution
and the quotient of
Revolutions
numerator / Revolutions
denominator
can be a decimal number.
The position value output is calculated with a zero point correction, the count direction
set and the gearbox parameter entered.
8.4.3.29.1 Attribute 101, Total Measuring Range
Total Measuring Range
defines the
total number of steps
of the measuring
system before the measuring system restarts at zero.
