Technical specifications
7.1 Overload capability of the inverter
Load cycles and typical applications:
"Low Overload" load cycle
The "Low Overload" load cycle assumes a
uniform base load with low requirements
placed on brief accelerating p phases. Typi-
cal 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
Typical inverter load cycles

"High Overload" load cycle
The "High Overload" load cycle permits, for
reduced base load, dynamic accelerating
phases. Typical applications when desig-
ning according to "High Overload" include:
• 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
