3. Instruction Set<br />

Application 3:<br />

Using auto-tuning for temperature control<br />

Control purpose:<br />

Calculating optimal parameter of PID instruction for temperature control<br />

Control properties:<br />

Users may not be familiar with a new temperature environment. In this case, selecting<br />

auto-tuning (S 3 +4 = K3) for an initial adjustment is suggested. After initial tuning is completed,<br />

the instruction will auto modify control mode to the mode exclusively for adjusted temperature<br />

(S 3+4 = K4). In this example, the control environment is a heating oven. See the example<br />

program below.<br />
