Functionality
Setting HO/LO overload enables you to select the low-overload mode for pumps and fans,
the most important target applications of SINAMICS V20 converters. Low-overload mode
can improve the rated output current of the converter and therefore allows the converter to
drive motors of higher power.
Typical application fields
● High overload: conveyors, agitators and centrifuges
● Low overload: pumps and fans
