WARNING
You can set a new value next to this
if Class 2 functionality
the set resolution value is enabled and used by the encoder; on the
contrary, if Scaling function
new resolution value, however it is not enabled even if sent to the
encoder: the encoder still goes on using the default value uploaded
from the GSD file, NOT the new entered value, until you enable the
Scaling function. See the section "6.4.1. Byte 10 – Operating
parameters" on page 31.
Counts per revolution
singleturn resolution (i.e. the desired number of information per
revolution).

Data
You are allowed to set any integer value less than or equal to the
Hardware counts per revolution. However we suggest setting a value
that is a power of 2 (1, 2, 4, ... 2048, 4096, ...).
Default = 4096 (min. = 1, max. = 8192) for AMT58 multiturn encoder
WARNING
If you set a value greater than the maximum allowed value (i.e.
greater than the Hardware counts per revolution value), the encoder
falls into an error signalling the faulty condition through the diagnostic
LEDs (see on page 13).
WARNING
When you set a new value next to the
please always check also the
that the resulting number of revolution complies with the Hardware
number of revolutions of the device.
Let's say our encoder is programmed as follows:
Counts per revolution: 8192
Total resolution= 33554432
Let's set a new singleturn resolution, for instance
revolution= 360.
If we do not change the
