WARNING
You can set a new value next to the
only if Class 2 functionality
control = ENABLED the set resolution values are enabled and used
by the encoder; on the contrary, if
DISABLED 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
control.
See the section "6.4.1 Byte 10 – Operating parameters" on page 23.

revolution).

Allowed values are equal to or lower than Hardware counts per
revolution value. We suggest setting power of 2 values (1, 2, 4, ...
2048, 4096, ...).
Setting a value greater than allowed causes the resolution to be
forced to Hardware counts per revolution value.
Default = 262144 (min. = 1, max. = 262144) for HS58
Default = 65536 (min. = 1, max. = 65536) for HM58
WARNING
When you set a new value next to
please always check also
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
trovata. value at the same time, we will get the following result:
