Typical applications with alternating load
All applications are affected for which a torque reversal with a sign reversal can be generated via the
motion profile. In practice, however, these applications can be narrowed down fairly well.
The applications given in the table can be dimensioned with the DSD.
Typical applications without alternating load
For the following applications, an operation with alternating load is improbable.
Application
Information
Motion applications:
Basically all motion applications (wheel drive, belt drive, rack drive, spindle
drive, rotary table drive, hoist drive with counterweight, general rotary drive
with motion profile) are affected, irrespective of whether they are actuated
by means of frequency inverters or servo inverters.
• Usually there is always a sign reversal in the case of the torque at the out-
put end.
Application
Information
Hoist drive without counterweight
For cable-guided hoists without counterweight no periodic alternating load
occurs. Only a repeated load cycle can occur.
Continuous conveyor
For continuous conveyors, no periodic alternating load occurs. Only a repeat-
ed load cycle can occur.
Pump, fan
For pumps and fans, no periodic alternating load occurs. Only a repeated
load cycle can occur.
Synchronous drive
Synchronous drives generally are quasi-stationary drives. There is no period-
ic alternating load. Usually there is only a repeated load cycle, unless these
drives are traversed in intermittent operation.
