Current derating as a function of the pulse frequency
In the factory setting, the drive starts with a pulse frequency of 4 kHz and reduces
automatically the pulse frequency to the associated required frequencies when loaded.
When the load decreases, the pulse frequency is increased automatically up to 4 kHz.
The values of the rated current apply to a pulse frequency of 2 kHz at 40° C ambient
temperature and are reached at any time by the automatic adaptation of the output pulse
frequency.
