8.3 Predefined motion profile according to operating mode

For the selection of the motor, the operating mode is important. A motor, for instance, heats up less

when loaded for a short time than when loaded continuously, and therefore it can be selected

smaller.

• It is advisable to use the motion profile for steady-state operation. Acceleration processes can

be taken into consideration. The motion profile is repeated in a cyclic manner.

• The predefined motion profiles are based on the operating modes in accordance with VDE 0530

or IEC 34-1.

• The DSD offers the selection of the operating modes S1, S2, S3 and S6.

• Operation of a motor in modes other than S1 may be run at a higher power level.

8.3.1 S1, continuous operation

Operation with a constant load that is available until the machine reaches the thermal steady state.
