Parameter Descriptions 2-191
7000-TD002A-EN-P – September 2007
Process Variable Eng [Process Var Eng]
Linear Number: 366
Minimum Value: -3276.7
Maximum Value: 3276.7
Access Level: Advanced
Read/Write: Read Only
This parameter displays the feedback from the process in engineering units according to the application.
PID Gain [PID Gain]
Linear Number: 353
Default Value: 1.00
Minimum Value: 0.00
Maximum Value: 655.35
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the proportional gain in the PID controller when Indpndt Gain option in PID
Command (313) is chosen. If not, this parameter represents controller gain. The proportional gain works
only on the proportional term while the controller gain works for all three terms, proportional, integral and
derivative, at the same time. Refer to the formula in the Manual to understand the difference between the
independent gain and the dependent gain.
PID Integral Time [PID Intgral Time]
Linear Number: 354
Default Value: 1.00 sec
Minimum Value: 0.00 sec
Maximum Value: 655.35 sec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the integral time constant in seconds. This parameter represent the time for the
integral term to repeat the action of the proportional term in response to a step change in error. A larger
value of this parameter causes a slower integral response.
PID Derivative Time [PID Deriv Time]
Linear Number: 355
Default Value: 0.00 sec
Minimum Value: 0.00 sec
Maximum Value: 655.35 sec
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the derivative time constant in seconds. A larger value of this parameter causes
a faster derivative response. If this value is set to 0, the derivative term in the PID controller is disabled.
Process Setpoint [Process Setpoint]
Linear Number: 360
Default Value: 0.5000 pu
Minimum Value: -2.0000 pu
Maximum Value: 2.0000 pu
Access Level: Advanced
Read/Write: Read/Write
This parameter specifies the process setpoint value.
