Resolution of the distance measuring system

For conversion of the increments delivered by the distance measuring system to the metric system (the unit used internally), the conversion factor must be entered in the two entries getriebe[x].wegaufz and getriebe[x].wegaufn. Thereby also eventually available gears must be considered. The resolution is specified as a fraction, and the dimension is increments/0.1 μm or increments per 0.0001°.

Example 1:

In the case of an incremental encoder with 4096 and a spindle lead of 5 mm, the resolution is 4096 increments per 5 mm. Therefore, the following entry must be made in the axis parameter list:

getriebe[0].wegaufz 4096

getriebe[0].wegaufn 50000

Example 2:

If additional a gear is used with a transmission ratio of i = 10:1, per motor revolution this results in 5 mm / i. Therefore, the following entry must be made for wegaufz and wegaufn:

getriebe[0].wegaufz 4096

getriebe[0].wegaufn 5000

Resolution of the distance measuring system 1:

This entry does not become directly active when the axis parameter list is updated. The control system must be restarted.

Resolution of the distance measuring system 2:

For SERCOS-drives with position controller in the CNC the resolution of the distance measuring system should be accounted in the feed constant S-0-0123 so that the quotient P-AXIS-00234removed link: P-AXIS-00234/P-AXIS-00233 results to one.
