WARNING
When you set a new value next to the
always check also the
sure that the resulting number of revolutions complies with the
Hardware number of revolutions of the device.
Let's say our encoder is programmed as follows:
revolution: 8192
Counts per
Total resolution
Let's set a new total resolution, for instance:
As the

revolution, the above setting is not allowed. When this happens,
per
the encoder falls into an error signalling the faulty condition through
the diagnostic LEDs (see on page 12).
