Under operating conditions a machine may sometimes have to be operated outside the limits
of range A.
● Exceeding the permissible tolerances for voltage and frequency can lead to an
impermissibly high temperature rise of the winding. This can result in long-term damage to
the machine.
● Limit exceptions of this sort with regard to the values that arise, how often, and for how long
they occur.
● Where possible and within a reasonable time take corrective actions such as reducing the
power. In this way you can avoid that the service life of the machine is reduced as a result
of thermal aging.
4.6 Phase synchronization during supply system switching
Damage to the machine may be caused when switching to another supply system with different
phasing.
● The phasing must be synchronized during switching. Use appropriate means to
synchronize the phasing.
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, such as line switching operations with a
residual field or short circuit at the terminals, excessive air gap torques can occur. These
excessive air gap torques can lead to additional mechanical torsional loads on 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, make due allowance for the maximum air gap torques that can
occur. This data can be found in the "Electrical data".
The system planner is responsible for the entire drive train.
