Standard dimensioning
If the motor data are not precisely known, then the converter
should be dimensioned based on the rated output current for
typical induction motors. If current derating is required, then the
derating factors are applied to this rated output current. The cur-
rent derating when converter units are operated in parallel has
already been taken into account for the values in the selection
and ordering data table.
Higher output currents are also possible under certain condi-
tions;
refer to the following section
.
Detailed dimensioning
If the motor data are more precisely known, then the converters
can also be operated with higher output currents. In this case,
the rated motor current must lie below the maximum thermal
converter output current, and the motor short-circuit current
must be less than the maximum permissible motor short-circuit
current of the converter.
Note:
The motor short-circuit current is the current that flows in a
system in the first 100 ms if all subsystems are short-circuited
and the leakage paths are saturated.
For higher rated output currents, the type-specific technical data
can differ. Please contact your regional Siemens sales partner if
you have any questions on this topic.
During the detailed dimensioning phase, derating factors should
be applied to the maximum thermal converter output current.
The current derating when converter units are operated in paral-
lel has already been taken into account for the values in the
selection and ordering data table.
