AMT58x-PB Profibus®
As you can see, the encoder is required to carry out more than
93000 revolutions, this cannot be as the hardware number of
revolutions is, as stated, 16384. When this happens, the encoder
falls into an error signalling the faulty condition through the diagnostic
LEDs (see on page 12).

WARNING
You can set a new value next to the
Class 2 functionality
ENABLED the set resolution values are enabled and used by the
encoder; on the contrary, if
you are allowed to set new resolution values, however they are not
enabled even if sent to the encoder: the encoder still goes on using
the default values uploaded from the GSD file, NOT the new entered
values, until you enable the
section "6.4.1 Byte 10 – Operating parameters" on page 23.
This parameter is intended to set the number of distinguishable steps
over the total measuring range. The total resolution of the encoder
results from the product of
revolutions.

Allowed values are equal to or lower than the Total hardware
resolution value.
Setting a value greater than allowed causes the resolution to be
forced to the Total hardware resolution value.
Number of revolutions =
We recommend the Number of revolutions to be set to a power of 2.
This is meant to avoid problems when using the device in endless
operation (when crossing the physical zero) and entering the "Red
Zone" (see the section "6.9 Red Zone").
