4.9 System-inherent frequencies
NOTICE
Machine damage caused by system resonances
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. The vibration limit
values according to DIN ISO 10816-3 must not be exceeded.
4.10 Torsional loading of the drive train 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.
Note
The system planner is responsible for the entire drive train.
WARNING
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.
Note
More information about this may be found in the catalog.
4.11 Transport and storage
When carrying out any work on the machine, observe the general safety instructions
(Page 15) and the specifications contained in EN 50110‑1 regarding safe operation on
electrical equipment.
