Description
revolutions O; default = 1 Integer >0 Number of
revolutions
that are used
when
calculating
valid positions,
for example, if
there is a gear.
osetRev O; default = 0 Float Desired end
rotor position
relative to the
nearest
physical
position. The
reference-
position is
determined by
the absolute
position at the
beginning of
this segment
and the
partition/
revolutions.
Given in
revolutions of
the axis.

Action: Log Value
This action is used to log values at specic points in the
CAM for later readout. All parameters that are available in
the object dictionary can be logged.
There are 16 memory cells available for logging. The
information is not automatically read out. This must be
done by the application. Memory cells are in object 0x3870
(see chapter 7.14.16 Parameter: Logged Values (0x3870)).
<logValue index="0x2020" sub-index="0x01"
memory="1"/>
The data must be interpreted according to the data type
of the value.
