● Example 3 Simple pattern
◆ Explanation
When the [ mode ] key is pressed, the mode is changed to the RUN mode and the
PV is started.
The SP value moves up (or down) along with the up/down ramp set value.
When the SP value reaches the final SP value and the PV value enters the constant
range, the counting is started. After the T2 time has elapsed, the mode is changed
to the READY mode.
