4.6
Rotational speed limit values
Excessive rotational speed can lead to serious damage to the machine and the converter. This
can result in death, serious injury or material damage.
● The converter control must ensure that operation at impermissible speeds is prevented.
● Please note the speed data specified in the Electrical Data.
4.7
System-inherent frequencies
Excessively high vibration levels 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 values according to DIN ISO 10816-3 must not be exceeded.
4.8
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.
Risk of torsional stress on the drive train
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. The system planner is
responsible for the entire drive train.
