Let's say our encoder is programmed as in EXAMPLE 2EXAMPLE :
Counts per revolution: 8192
Total resolution= 33554432
resolution (high) = 512; Total resolution (low) = 0
Let's set a new singleturn resolution, for instance: Counts per
revolution = 360.
If we do not change the Total resolution value at the same time, we
will get the following result:
Number of revolutions =
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).
You are allowed to set any integer value less than or equal to the
Hardware counts per revolution in the Counts per revolution item;
while you are allowed to set any integer value less than or equal to
the Hardware counts per revolution in the Counts per revolution item;
however we suggest always setting values that are a power of 2 (1,
2, 4, ...2048, 4096, ...).
