The following example serves to illustrate the approach:
Given:
-
Measuring system with 4096 steps/rev. and max. 4096 revolutions
-
Resolution 1/100 mm
-
Ensure the measuring system is programmed in its full resolution and total
measuring length (4096x4096):
Total number of steps
= 16777216,
Revolutions numerator
= 4096
Revolutions denominator = 1
-
Set the mechanics to be measured to the left stop position
-
Set measuring system to "0" using the adjustment
-
Set the mechanics to be measured to the end position
-
Measure the mechanical distance covered in mm
-
Read off the actual value of the measuring system from the controller
connected
Assumed
:
-
Distance covered = 2000 mm
-
Measuring system actual position after 2000 mm = 607682 steps
Derived:
Number of revolutions covered
= 607682 steps / 4096 steps/rev.
=
148.3598633 revolutions
Number of mm / revolution = 2000 mm / 148.3598633 revs. =
13.48073499mm / rev.
For 1/100mm resolution this equates to a
Number of steps per revolution
of
1348.073499
Required programming:
Number of Revolutions numerator
=
4096
Number of Revolutions denominator =
1
Total number of steps = Number of steps per revolution *
Number of revolutions numerator
Number of revolutions denominator
= 1348.073499 steps / rev. *
4096 revolutions numerator
1 revolution denominator
=
5521709 steps
(rounded off)
