Derating of the output current as a function of the pulse frequency
With the factory setting, the drive starts with a 4 kHz pulse frequency, and under load,
automatically reduces the pulse frequency step-by-step to the frequencies required. 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.
