System overview
2.10 Derating data
Note
Derating factors for pulse frequencies in the range between fixed values
For pulse frequencies in the range between the specified fixed values, the relevant derating
factors can be determined by linear interpolation.
Additional information is provided in the "SINAMICS Low Voltage Engineering Manual"
provided on the customer DVD supplied with the unit.
Maximum output frequencies achieved by increasing the pulse frequency
By multiplying the rated pulse frequency with a multiple integer, the following output
frequencies can be achieved taking into account the derating factors:
Table 2- 5
Table 2- 6
Depending on the system configuration, higher frequencies are possible.
