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, 4096. When this happens, the encoder falls
into an error signalling the faulty condition through the diagnostic
LEDs (see on page 13).

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.

You are allowed to set any integer value less than or equal to the
Hardware total resolution. However we suggest setting a value that is
a power of 2.

If you set a value greater than the maximum allowed value (i.e.
greater than the Hardware total resolution value), the encoder falls
into an error signalling the faulty condition through the diagnostic
