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

"Low Overload" and "High Overload" load cycles
7.3 Overload capability of the inverter
"High Overload" load cycle
The "High Overload" load cycle permits, for
reduced base load, dynamic accelerating
phases. Typical applications when design-
ing 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
