Parameter to be used

Control type

Control type

In addition to PID control, this device is fitted with the fuzzy control
suitable for suppressing overshoot. One of the two can be selected as
the control type.

Setting procedure

(control type)

Select the control type.

NOTES:

1. When control is made with the fuzzy, the PID parameter must be set

as with PID control. However, it need not be tuned particularly for
the fuzzy. (The values are allowed to be the same as those for PID
control.)

2. The fuzzy control mode also allows use of the autotuning function.

3. Fuzzy control cannot be used in the dual output type.

4. The two-set-point function is not available in the fuzzy control mode.

5. Fuzzy control can only be used when the set values change in

steps. Attention is required when the ramp soak function or remote
SV function is used.
