Parameters and Programming 5-15

PI Control Block Diagram Figure 5.1

81 [PI Proportional Gain]

Proportional gain used by the PI regulator. This parameter is scaled so that when

it is set to 1.0, the process response is 1 Hz when the process error is 1%. The

correct value for this parameter depends on the dynamics of the process being

controlled, as well as the desired response. This parameter is active when

P46 - [Input Mode] setting 9 is used.

0/10.00 Numeric

Value

0.01

82 [PI Integral Gain]

Integral Gain used by the PI regulator. This parameter is scaled so that when it

is set to 1.0, the process response is 10 Hz/sec when the process error is 1%.

The correct value for this parameter depends on the dynamics of the process

being controlled, as well as the desired response. This parameter is active when

P46 - [Input Mode] setting 9 is used.

0/10.00 Numeric

Value

0.01

83 [PI Process Reference]

The PI control will regulate to this set point value. It represents a percentage of

the analog input. This parameter is active when P46 - [Input Mode] setting 9 is

used.

0/100.0% 0.1% 0.0%

84 [PI Dead Band]

The PI control will ignore errors less than this value. This parameter is active when

P46 - [Input Mode] setting 9 is used.

0/10.0% 0.1% 0.0%
