*2: Before executing program control, the PID constants of zone1 and zone2 need to be set by
the program control auto tuning (X11).
When program control is executed by the set pattern, it operates as follows.
Segment number
Segment 1
Segment 2
Segment 3
Segment 4
Process Value (PV)
150
50
Zone PID=2
Segment 1
200s
*3: After setting parameter by the cascade control setting command (X15), execute cascade
control by turning on the cascade control switching command (X8).
In this program example, the parameter setting for cascade control and the other parameter
settings (normal control, program control, and manual control2) cannot be set at the same
time.
After setting the parameter for cascade control, do not use the normal control mode switching
command (X4), program control mode switching command (X5), and manual control mode 2
switching command (X7).
