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 shaft assembly due to faults in the electrical
supply
In the event of faults in the electrical supply, such as e.g. line switching operations with a
residual field or short circuit at the terminals, excessive air gap torques can occur, which can
lead to additional torsional loads on the 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, make due allowance for the maximum air gap torques that can
occur. This data can be found in the "Electrical Data" in the appendix, in the "Transient
Torques" data sheet, or by inquiring at the Service Center.
Note
The system planner is responsible for the complete shaft train.
