Setting Control Specifications
Section 4-3
Note
The decimal point position is determined by the sensor selection. In this case,
however, the 0 (****) decimal point position setting will be treated as setting 1
(***.*).
Refer to
4-7-1 Bank Function
for details on banks.
■
Manual Reset Value
This parameter sets the required manipulated variable to remove the offset
during settling in P or PD control.
Note
Refer to
4-7-1 Bank Function
for details on banks.
Independent heating/
cooling PID method
When using the independent heating/cooling PID method, the heating and
cooling PID can each be set individually. Air cooling, water cooling, and linear
control methods can be selected depending on the control characteristics of
the cooling side. Also, autotuning (AT) will automatically set the PID constants
on the cooling side.
Note
For more information on autotuning, refer to
4-3-8 Tuning
.
Note
(1) Refer to
4-7-1 Bank Function
for details on banks.
(2) The decimal point position is determined by the sensor selection. In this
case, however, the 0 (****) decimal point position setting will be treated as
setting 1 (***.*).

Air cooling/water
cooling
Provides control for applications that have non-linear cooling
characteristics (e.g., plastic molding machines). Provides
good adaptability and stable response.
Linear
Provides control for applications that have linear cooling char-
acteristics.
