System-inherent frequencies

System-inherent frequencies
The system consisting of the foundation and machine set must be configured and matched
in such a way that no system resonances can arise and result in the permissible vibration
levels being exceeded.
Excessive vibrations can damage the machine set.
DIN 4024 must be taken into account when constructing the machine foundation. The limit
values to DIN ISO 10816-3 must not be exceeded.
4.10 Torsional loading of the shaft assembly due to faults in the electrical
supply
In the event of faults in the electrical connection during operation, excessive air gap torques
can lead to additional mechanical torsional load on the line shaft.
Serious damage to the machine
If the configuration does not correctly recognize the mechanical torsional loadings of the shaft
assembly, this can lead to serious damage to the machine. This can result in death, serious
injury or material damage.
When planning the system, consider the configuration data in the catalog.
Note
The system planner is responsible for the entire shaft assembly.

Transport and storage

When carrying out any work on the machine, observe the general safety instructions and the
specifications contained in DIN EN 50110‑1 as regards working safely with and on electrical
machines.
