SFA-5000 • SFA-10000 DeviceNet
Let's say that the transmitted position value is 123.
Thus the linear position value will be as follows:
Linear position value
= transmitted position * linear resolution
Linear position value
= 123 * 0.024 = 2.952 mm = 2,952 µm
EXAMPLE 2
Let's suppose that we are using the SFA-5000-FD-8192-PG draw-wire encoder.
The singleturn resolution is set to the custom value of 4,000 cpr (
= 4000). The transmitted position value is 1,569.
The linear resolution can be easily calculated as follows:
Linear resolution
=
200
= 0.05 mm = 50 µm
4,000
Thus the linear position value will be as follows:
Linear position value
= 1,569 * 0.05 = 78.45 mm = 78,450 µm

3 Counting direction
3 Counting direction
attribute sets whether the position value output by the
encoder increases (count up information) when you rewind the wire (0) or when
you pull the wire out (1, default).
0: rewinding the wire the position will increase;
1: pulling the wire out the position will increase.
Default = 1 (min. = 0, max. = 1)

then you are required to set a
attribute) and finally save the new
parameters (see the “5.4 Saving the parameters with RSNetWorx“ section on
page 33).
