Current derating as a function of the pulse frequency
If the drive is set to operate at increased pulse frequencies,
the output current values listed in the technical specifications
must be derated in accordance with the tables below.
(Note that SINAMICS G150 can be set up to operate at
higher pulse frequencies when permitted by ambient
and load conditions, and automatically lower the pulse
frequency to avoid overtemperature – in this case derating
is not necessary).

Calculating derating factor by means of linear interpolation.
For intermediate values of pulse frequencies, the relevant derating factors can be determined by means of linear interpolation.
The following formula applies to this:
