SFA-5000 • SFA-10000 Profibus
Never release the wire freely, always help the wire wind properly: risk of personal
injury and/or equipment damage.
Always keep the wire aligned not to damage the equipment (maximum
deviation: 3°).
3.3 Useful information
If you want to know the
maximum measuring length
and the
physical linear
resolution
of the draw-wire encoder please refer to the order code. The stroke
per turn is always 200 mm (7.874”), the maximum number of turns is 25 for
SFA-5000 and 50 for SFA-10000.
EXAMPLE 1
SFA-
5000
-
PB
-
8192
-PG using the physical resolution (
Scaling function
control
= 0)
Stroke per turn of the drum = 200 mm (7.874”)
Physical resolution per turn = 13 bits = 8,192 cpr
Max. number of physical revolutions = 4,096
Total physical resolution = 25 bits = 33,554,432 information
Physical linear resolution = 0.024 mm = 24 µm
Max. number of turns of the drum = 25
Max. measuring length = 5,000 mm (196.85”)
Number of information = 204,800
EXAMPLE 2
SFA-
10000

8192
-M12 using a custom resolution (
Scaling function
control
= 1)
Stroke per turn of the drum = 200 mm (7.874”)
Physical resolution per turn = 13 bits = 8,192 cpr
Max. number of physical revolutions = 4,096
Custom resolution per turn =
Counts per revolution = 2,000 cpr (example)
Total resolution = 8,192,000 information (example)
Custom number of encoder revolutions =
Total resolution
= 4,096
Counts per revolution
Linear resolution = 0.1 mm = 100 µm
