InitializeFlange

Initializes a flange with pre-defined position, speed and acceleration (usually, this is reference data from a control bus)

Description

This component is used to optionally initialize the position, speed,and/or acceleration of the flange to which this componentis connected. Via parameters use_s_start, use_v_start, use_a_startthe corresponding input signals s_start, v_start, a_start are conditionallyactivated. If an input is activated, the corresponding flange propertyis initialized with the input value at start time.

For example, if "use_s_start = true", then flange.s is initializedwith the value of the input signal "s_start" at the start time.

Additionally, it is optionally possible to define the "StateSelect"attribute of the flange position and the flange speed via parameter"stateSelection".

This component is especially useful when the initial values of a flangeshall be set according to reference signals of a controller that areprovided via a signal bus.
