1-1-4. Re-obtaining the Parameters after Replacement of the Magnescale
Follow the work steps stated in section 2.3, Y Setup of the MS parameters to obtain the offset
amount of the right origin position to the left origin position.
Make the correction so that the machine status becomes the factory-settings.
∗ “Y Setup” operation is performed based on the preconditions that the mechanical squareness
has been adjusted completely.
If the mechanical squareness deviates, it is necessary to adjust the mechanical squareness.
(See “X/Y Unit” in the QA Table.)
