Setting Control Specifications Section 4-3
Note The decimal point position is determined by the sensor selection. With analog
inputs, the decimal point position is determined by the Decimal Point Position
parameter setting. 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.
4-3-4 Setting the Set Point
These parameters set the set point.
Note Refer to 4-7-1 Bank Function for details on banks.
Set the set point so that it is within the input range as well as the set point lim-
iter range.
If the set point is out-of-range, the internal set point actually used for control
will be limited to a value within the input range and set point limiter range.
■ Set Point Limiter
These parameters apply a limit to the set point's setting range so that the con-
trol subject does not reach an abnormal temperature.
Note Set the SP Upper and Lower Limits within the input range and also set the SP
Upper Limit > SP Lower Limit.
If the SP Lower Limit > SP Upper Limit, the larger value will function as the SP
Upper Limit. In addition, if the limit range is set outside of the input range, it
will be limited to the input range.
The SP will not be changed automatically, even if the input type or SP Limiter
is changed. Although the SP will not be changed automatically, the internal
SP used for control will be limited to the input range or SP Limiter (whichever
range is narrower).
