Set the control mode.
Control stop (RdY): Primary/secondary operating amount limiter lower limit is output.
Control start (RUN): Normal control is executed.
Manual (MAN): Operating amount set in the primary/secondary operating amount is output.
Timer interlocking control (tIME 1 to 3): A control where the normal control and timer operation are interlocked is executed.
For start (RUN)/stop (RdY)/manual (MAN) of control, see section “5.4.3 Mode/manual function” on page 5-28.
For timer interlocking control (tIME 1 to 3), see section “5.4.5 Timer function” on pages 5-32 to 37.

Set the control type (method).
Control types of primary and secondary control outputs that are set on this equipment can be assigned to the methods of 0 to 6.
For the content of the assignment, see the setting content listed above.
Note
(1) In case that the control type is set to 3 (primary/secondary PID control) and the tuning type to 3, 4 or 5, take care that the tuning
type changes to 1 (primary tuning) in conjunction with the change of the control type.
(2) Take care that the position proportional control (CNt: 6) is selectable even when the primary/secondary control output is not set
for the target connection setting.

Set the PID control type.
For the use of the equipment in setting of the control type to be the PID control, a selection can be made among three control types of
0 (type A) to 2 (type C), whichever is best suited for the application.
Note The type B mode can be set when the PID control type is set to 1 (type B). In the type B mode, a result from integration (I) or
differentiation (d) of the auto-tuning is multiplied by a coefficient. The intermediate type is same value as it is. The type C
(disturbance suppression function) cannot be set when the self-tuning is set in the tuning type setting.
For control characteristics of each control type, see section “5.4.1 Auto-tuning (AT) function” on pages 5-23 to 25.
