WARNING
When you enable the scaling function (
Scaling function control
= 1), please
enter scaled values next to the
Counts per revolution
and
Total resolution
parameters that are consistent with the physical values. In the case of
inconsistent values, the system does not go online and visually warns about the
wrong parametrization and fault condition by means of the diagnostic LEDs.
WARNING
Every time you change the value in this parameter, then you are required to set
a new preset value (see the
Preset value parameter).

WARNING
This is only available when the encoder Class 2 or the encoder Class 2 (+VEL) are
installed (see the SFA-x-PB-8192 Class 2 or SFA-x-PB-8192 Class 2 (+VEL)
submodules).
You can activate a new value next to the
Total resolution
item only if
Class 2
functionality
= ENABLED. If
Scaling function control
= ENABLED the set
resolution values are enabled and used by the encoder; on the contrary, if
Scaling function control
= 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 physical values, NOT the new entered values, until you
enable the
Scaling function control . See the “6.4.1 Byte 10 - Operating
parameters” section on page 48.
If
Class 2 functionality
= DISABLED or
Scaling function control
= DISABLED,
then the system uses the physical values to arrange the position information.
This parameter is intended to set a custom number of distinguishable steps over
the total measuring range. The
Total resolution
of the encoder results from the
product of
Counts per revolution
by the required
Number of revolutions
.
