The Robo Cylinder can also store points that are executed as incremental moves instead of point to point moves. These increment moves simply change the current position by the amount that is stored in the incremental move.

In the example the point table has ten taught positions. The first two are point to point moves that, when executed, will position the actuator at the 0mm or 100mm, depending on which position has been executed. The rest of the positions are considered incremental moves.

To define an incremental move the position must have a "1" entered in the "ABS/INC flag" column. Once defined as such, the position, when executed, will move the actuator to a distance away from its current position. The distance is equal to the value in the "Position" column. A negative value cannot be entered in the "Position" column in a point to point move. To enter a negative value in the "Position" column for a incremental move, the value in the "ABS/INC" column must first be "1".

As an example let us consider the execution of positions 0, 5, 4 and 3. The first movement is a point to point move to 0mm. The second move is an incremental move that will have an ending point of 10mm. The third movement is an incremental move that will have an ending point of 15mm. The fourth move is an incremental move with an ending point of 16mm.

As the second example, let us consider the execution of positions 1, 9, 8, 7. The first movement is a point to point move to 100mm. The second move is an incremental move that will have an ending point of 90mm. The third movement is an incremental move that will have an ending point of 85mm. The fourth move is an incremental move with an ending point of 84mm.

With two incremental moves the Robo Cylinder can move back and forth across its entire stroke length, if a PLC triggers the incremental moves enough times. If the PLC tracks the execution of incremental moves, it is easy to achieve more than 16 distinct points.
