7.2.3 Motion of the application

For the calculations, the motion must be taken into consideration. A distinction is made between

the predefined and the user-definable motion profile.

• User-definable motion profile:

• The motion profile is based on the standardised S8 … S10 operating modes according to

VDE 0530.

• For calculating the motion profile the parameters at each time have to be calculated.

• The maximum values for power, torque, and speed are important reference values for the cal-

culation of the motion profile.

• The motion profile can be created graphically, defined based on numerical values or be im-

ported.

• Predefined motion profile:

• The motion profile is based on the standardised S1 … S7 operating modes according to

VDE 0530.

• For the calculation, apart from the stationary status also dynamic processes are taken into

consideration.

• The predefined motion profile provides a simple possibility of entering a motion profile with

acceleration, constant travel, deceleration, and standstill.

• The settings "Brake at standstill" and "Controller inhibit at standstill" can be selected.

• The parameters "Delay time", "Starting time", "Cycle time", and "Direction of movement" can

be altered.
