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.
