Two typical duty cycles are de󹪝ned to select and dimension a converter to match the
application.
"Low Overload" duty cycle
The "Low Overload" duty cycle 󹪝ts a uniform
base load with low requirements placed on
brief acceleration phases.
 "High Overload" duty cycle
The "High Overload" duty cycle permits dy‐
namic acceleration phases at a reduced con‐
tinuous load.
If not speci󹪝ed otherwise, the power and current data in the technical data always refer to a
duty cycle with Low Overload.
Example
Typical applications for the two duty cycles:
"Low Overload" duty cycle  "High Overload" duty cycle
Typical applications when designing accord‐
ing to "Low Overload" include:
• Pumps, fans and compressors
• Wet or dry blasting technology
• Mills, mixers, kneaders, crushers or agita‐
tors
• Basic spindles
• Rotary furnaces
• Extruders
 Typical applications when designing accord‐
ing to "High Overload" include:
• Horizontal and vertical conveyor technol‐
ogy, e.g. conveyor belts, roller conveyors,
chain conveyors
• Centrifuges
• Escalators/moving stairways
• Lifting or lowering equipment
• Elevators
• Gantry cranes
• Cable railways
• Storage and retrieval machines
More information
We recommend using the "TIA Selection Tool" con󹪝guring software to select the converter.
