Setting the Set Point

Proportional Band
When this parameter is set to Enabled, the proportional band is increased by
a factor of 10. Use this parameter when the proportional band setting range is
insufficient.
Variable type
F0/B0
Conditions for use
Note This parameter can be set only while operation is stopped.
When this parameter has been changed, the new setting becomes effective
the next time a software reset is performed for the Unit or the next time power
is turned ON.
Setting the Alpha
This parameter sets the 2-PID constant alpha ( ).
Note Normally, this parameter is left at its default value.
Variable type
D5/95
Conditions for use
These parameters set the set point.
Variable type
D0/90
Note (1) Refer to 5-7-1 Bank Function for details on banks.
Set the set point so that it is within the input range as well as the set point
limiter range.
If the set point is out-of-range, the internal set point actually used for con-
trol will be limited to a value within the input range and set point limiter
range.
(2) The decimal point position is the same as set for the Decimal Point Posi-
tion B parameter.
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.
Variable type
D5/95
Conditions for use
Note (1) 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.
