Siemens SINAMICS G120XA - Load Cycles and Overload Capability; Base Load; Permissible Converter Overload

11.2 Load cycles and overload capability
Overload capability is the property of the converter to temporarily supply a current that is higher
than the rated current to accelerate a load.
Definitions
Base load
Constant load between the accelerating phases of the converter
LO base load input current
Permissible input current for a "Low Overload" load cycle
LO base load output current
Permissible output current for a "Low Overload" load cycle
LO base load power
Rated power based on the LO base load overload output current
If not specified otherwise, the power and current data in the technical data always refer to a load
cycle according to overload.
Permissible converter overload
Rated overload is based on a duty cycle of 110 % for 60 s.
