The initial resolution corresponds to an encoder increment. As this is usually not an integer, it is expressed in the form of the following ratio:
RESOL = Distance / No. of points where:
-
Distance = distance covered by the moving part
-
No. of points = number of encoder points corresponding to the distance covered. The threshold is 1 to 1,000,000.
The resolution is then deduced from these 2 parameters (Distance and Nbre points) in a ratio of 0.5 to 1,000.
Resolution Calculation Example
Either an incremental encoder of 512 points per turn. The distance covered by 1 encoder turn is 10,000 microm (microm = chosen length unit).
You must enter:
-
Distance = 10 000,
-
Number of points = 512
The resolution is then 19.5 microm:
NOTE: You can correct this resolution in the adjustment screen. It is therefore called the initial resolution.
In the case of an incremental encoder with multiplication by 4, enter the distance corresponding to
