When the entire measuring range was traversed, the reference mark and the limit and homing
switching points are displayed.
Note
Limit plates mark the measuring range at the machine. Thus, they may only be "approached"
until a switching point is detected. Traversing the plate falsifies the calculation of the limit.
Note
For tolerances see mounting instructions of the encoder.
