Note
Derating factors for pulse frequencies in the range between two fixed values
For pulse frequencies in the range between the specified fixed values, the relevant derating
factors can be determined by linear interpolation.
Maximum output frequencies achieved by increasing the pulse frequency
The adjustable pulse frequencies - and therefore the output frequencies that can be achieved
with the factory-set current controller clock cycles - are listed below.

1.25 kHz:
- 510 ... 720 V DC: ≥315 kW / 605 A, with the exception of 6SL3320-1TE41-4AS3
- 675 ... 1035 V DC: All power ratings
With the "High output frequencies" license, which can be ordered as option J01 on the CompactFlash card for SINAMICS

S120, the maximum output frequency is increased up to 650 Hz.
Refer to the Low Voltage Configuration Manual for current controller clock cycles deviating
from the factory setting.
