Procedure for acceptance of the position values

It is always necessary to check the position values as they are the basis for the speed and acceleration values. Proceed as follows to accept the correct encoder resolution and conversion into user units:

  1. Set a starting point for a movement, e.g. a reference point.
  2. Mark the starting point.
  3. In MOVISUITE®, read the positions of the utilized encoders in the [Diagnostics] > [MOVISAFE CS..A] > [Encoder Evaluation] dialog and log them.
  4. Travel a defined distance (e.g. 5 m).
  5. Mark the target point.
  6. Measure the traveled distance using a suitable measuring instrument (e.g. magnetic tape).
  7. In MOVISUITE® in the dialog [Diagnostics] > [MOVISAFE® CS..] > [Encoder Evaluation], read the position values of the utilized encoders again and log them.
  8. Calculate the traveled distance from the difference of read-out values and compare the result with the measured distance.
  9. If both values are identical, the following is accepted:
    • Position values in user units
    • Encoder resolution
    • Gear unit ratio and other ratios
    • All other mechanical elements that have an influence on the position values, such as diameter of the drive wheel.
