Let's set a new singleturn resolution, for instance:

360 (
As you can see, the encoder is required to carry out more than 93,000
revolutions, this cannot be as the hardware number of revolutions is, as stated,
4,096. When this happens, the encoder falls into an error signalling the faulty
condition through the diagnostic LEDs (see on page 26).
WARNING
When you enable the scaling function (
23-01-0E Scaling function control
01), please enter scaled values next to the
23-01-11 Total measuring range
consistent with the physical values. In the case of inconsistent values, the
system will warn about the wrong parametrization and fault condition by
means of the dedicated attributes and visually by means of the diagnostic LEDs.
WARNING
Every time you change the scaled values (see the
23-01-11 Total measuring range
required to set a new preset value (see the
attribute).

WARNING
This attribute is active only if the
23-01-0E Scaling function control
is set to ”=01”; otherwise it is ignored and the system uses the physical values
(
23-01-2A Hardware counts per revolution
) to calculate the position information.
This attribute sets a custom number of distinguishable steps over the total
measuring range. In other words, this attribute allows to set the length of the
travel the encoder has to measure expressed in number of distinguishable steps
(number of information). The total resolution of the encoder results from the
