Current derating for SINAMICS S150 drives as a function
of the pulse frequency
For control performance reasons or to increase output
frequency, the pulse frequency can be increased relative
to the factory setting. When the pulse frequency is
increased, the output current needs to be derated. This
derating factor must be applied to the currents specified
in the technical data.
An increased pulse frequency may also be used to reduce
motor noise. Note that SINAMICS S150 firmware also
includes functionality that allows an increased pulse
frequency without derating, when conditions permit (load,
ambient temperature, and input voltage). The pulse
frequency is
automatically reduced if the drive approaches
its thermal limits.
For additional information, please refer to the SINAMICS Low
Voltage Engineering Manual.
