After you click the "Set" button the datum is saved in the encoder memory.
Note
This setting is used for purely serial measuring systems (i.e. encoders that do not output any
incremental signals; interface names EnDat 22 and EnDat 21).
Note
Before the datum shift is performed, the measuring system must be positioned to the point
at which the new datum should be set.
