Limit Switch Outputs (continued)

Stitch Programming

Stitching allows you to create a regular on/off pattern within a setpoint pair. One application of stitching is
placing a glue pattern on a box before it is sealed. Figure 2.3 shows a single limit switch where the first set-
point pair uses a stitching pattern and the second setpoint pair does not.

Figure 2.3 Stitched Limit Switch Output

The most common way of programming a stitched output is to determine the required On Distance, the
required Off Distance, and the number of times the output must be on. Once the From Setpoint is determined,
the To Setpoint is then calculated as:

When programming a stitched output, you do not enter the number of times the output turns on and off. The
ANS1 calculates the number of times the output changes state based on the programmed On Distance, Off
Distance, and From and To Setpoints. The ANS1 will give a programming error if the four programmed
parameters do not allow the On Distance to occur at least twice and the Off Distance to occur at least once.

Figure 2.3 shows Stitch ON and Stitch OFF distances that were chosen to fit evenly within the From and To
setpoints. It is possible to program the parameters so that the distances do not fit evenly. Two examples are
shown in figure 2.4.



If the remaining distance in the From/To setpoint pair is greater than or equal to one half of the Stitch
ON distance, the output will come on at the end of the limit for the remaining distance.



If the remaining distance in the From/To setpoint pair is less than one half of the Stitch ON distance, the
output will be off at the end of the limit for the remaining distance.
