The function block adds an absolute linear movement to the table of segments in the PathData structure. After creating a table, it can be executed via MC_MovePath. The function block MC_MoveLinearAbsolutePreparation can be called several times per cycle. A maximum of 30 entries are allowed per PathData table.

---|---|---|
Position | POINTER TO LREAL | Pointer to an array [1..PositionCount] of the target position vector. |
PositionCount | UDINT | Dimension of the position vector. Must match the number of axes in the axis convention (see MC Group Coordinated Motion or MC Group with Pick-and-Place). |
Velocity | MC_LREAL | The maximum velocity for the programmed segment. The velocity does not always have to be reached. The velocity must be set >0. |
Acceleration | MC_LREAL | Maximum path acceleration for the programmed segment. Special input values can be used. MC_DEFAULT executes the command with default axis values. MC_MAXIMUM executes the command with the maximum axis values. The acceleration must be set ≥1. |
Deceleration | MC_LREAL | Maximum path deceleration for the programmed segment. Special input values can be used. MC_DEFAULT executes the command with default axis values. MC_MAXIMUM executes the command with the maximum axis values. The deceleration must be set ≥1. |
Jerk | MC_LREAL | Path jerk for the programmed segment. Special input values can be used. MC_DEFAULT executes the command with default axis values. The jerk must be set ≥100. |
BufferMode | MC_BUFFER_MODE | Defines how successive motion commands are to be processed (see MC_BUFFER_MODE). |
Transition mode | MC_TRANSITION_MODE | Defines the blending mode (see MC_TRANSITION_MODE). |
TransitionParameter | POINTER TO LREAL | Pointer to array [1..TransitionParameterCount] of blending parameters. Transition parameters define the blending from the last programmed position (see MC_TRANSITION_MODE). |
TransitionParameterCount | UDINT | Number of blending parameters (see MC_TRANSITION_MODE). |
InvokeId | UDINT | Segment ID for analysis purposes. |
