Siemens SIMOTICS DC 1GG5 - Schematic Diagram: Aligning the Machine to the Driven Machine

4. When positioning the machine, ensure that a uniform axial gap (y→0) is maintained around
the coupling.
5. Fix the machine to the foundation. The choice of fixing elements depends on the foundation
and is the plant operator's responsibility.
