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.
4.13
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.
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.

Transport and storage
When carrying out any work on the machine, observe the general safety instructions
