43 Chapter 4 Setting the Origins
4-2 Setting the Y-axis Origin
Step 1: Detect the A-axis Center
To set the Y-axis origin at the center of the A axis, you first perform detection of the A-axis center. You don't need to perform
this operation each time you set the Y-axis origin, but you must be sure to perform it once after installing the unit.
This operation includes various types of adjustments for compensation and correction. Changes in temperature and the like
can cause mechanical misalignment, and we recommend performing periodic detection to maintain accuracy.
