System-inherent frequencies
NOTICE
System resonances
Excessive vibrations and system resonances can damage the machine set.
● Configure and match the system consisting of the foundation and machine set in such a
● The vibration limit values according to DIN ISO 10816-3 must not be exceeded.
4.17
Torsional load of the drive train
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.
Torsional loadings of the shaft assembly
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
You can find more information in Chapter 2 of catalog D81.8.

Transport and storage
Observe the following when carrying out any work on the machine:
● Comply with the general safety instructions
● Comply with the applicable national and sector-specific regulations at the place of
● When using the machine within the European Union, comply with the specifications laid
