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)
