Load cycles and typical applications:
"Low Overload" load cycle
"High Overload" load cycle
The "Low Overload" load cycle assumes a
uniform base load with low
requirements
placed on brief accelerating phases. Typical
applications when designing according to
"Low Overload" include:
•
Pumps, fans and compressors
•
Wet or dry blasting technology
•
Mills, mixers, kneaders, crushers,
agitators
•
Basic spindles
•
Rotary kilns
•
Extruders
The "High Overload" load cycle permits
dynamic accelerating phases at a reduced
base load. Typical applications when de-
signing according to "High Overload" in-
clude:
•
Horizontal and vertical conveyor
technology (conveyor belts, roller
conveyors, chain conveyors)
•
Centrifuges
•
Escalators/moving stairways
•
Lifters/Lowerers
•
Elevators
•
Gantry cranes
•
Cable railways
•
Storage and retrieval machines

Motors for 200 V Power Modules
For the 200 V Power Modules, induction motors are permissible in the range from
25% … 150% of the converter power without any restrictions.
Permissible motors
Note
Motors for converter operation
Only use
motors that are suitable for operation with converters with a DC link.
