Parameterization and configuration
6.6.4 Scaling parameters, C__65_-EPN TR-Special / Cams / SSI
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.
6.6.4.1 Total measuring range
Defines the total number of steps of the measuring system before the measuring
system restarts at zero.
lower limit
upper limit
default
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.
To calculate, the parameters Steps per revolution and the Number of
revolutions can be read on the measuring system nameplate.

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
0 1
of the group 2 , 2 , 2
or
 Ensure that every positioning in the de-energized state for a multi-turn
measuring system is within 512 revolutions.
