4.10 Rotational speed limit values
WARNING
Excessively high speeds
Excessive rotational speed can lead to serious damage to the machine. This can result in
death, serious injury, or material damage.
● Avoid operation above the permissible speed by using the appropriate control function.
● Observe the speeds stamped on the rating plate.
4.11 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
way that no system resonances can arise and result in the permissible vibration levels
being exceeded.
● The vibration limit values according to DIN ISO 10816-3 must not be exceeded.
4.12 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
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.
