The following is the example of program pattern 1 controlled by the PID control in
the order of segment 1
2 3 4. This section explains the program pattern data,
control data, and zone PID data as an example.

1) Set the executed program pattern with the control data. Sets program pattern1.
2) Create the program pattern to be executed.
Set the information in the segment 1, 2, 3 and 4 of the program pattern 1, and
execute in the order of segment 1
2 3 4.
As the zone PID data used by each segment, set 2 for segment 1 and 2, and 1
for segment 3 and 4.
Set the segment 4 for the final segment which completes the program pattern.
3) Set the PID constants and control response parameters with the zone PID data
used for the PID control.
Set the PID constants and control response parameters for the zone 1 and zone
2.
