In this case, a new traversing block is only started if the previous block
had been completed, i.e. the drive has reached the reference position.

Selecting and starting the first traversing block
––> selected via ”block selection”
––> edge of ”activate traversing task” ––> ”setpoint acknowledgment” is set to a ”1” signal.
2
End of the first positioning operation,
––> ”setpoint acknowledgment” is reset
––> ”reference position reached” is set if the actual position is within the defined window
––> ”drive stationary” is set, if the speed is less than the speed limit for ”drive stationary”
The second traversing block is started

Note
The selection and the status of the block selection are not
binary–coded, but represented, simplified as value.
