Step 10: Ready, axis moved!

Motion of axis starts if value of variable “StartMotion” at FB MC_Move_Relative_1 is forced to value TRUE. Current position of the axis is displayed at output variable “Position” at FB MC_ReadActualPosition_1.

Figure below shows the state of FBs and variables at the end of the commanded motion. Value TRUE at output variable “Done” of FB MC_MoveRelative_1 informs us, that the motion is finished. “Done” remains TRUE until falling edge at input “Execute” is detected. We can do this by forcing value of input “Execute” to FALSE.
