C604: PID Feedback Input Selection
The PID feedback input can be selected from any of the 8 options. The various options include FSV 0-
10V, FSI 4-20mA, Vin 0-10V, Iin 4-20mA, PLC A-O/P 1, PLC A-O/P 2, PLC A-O/P 3 and PLC A-
O/P 4.. The option selected for the PID reference input cannot be selected for the PID feedback input.
The value of selected PID feedback input is displayed in M110 in %.
C605: Proportional Gain
This parameter is used to set the proportional gain for the P-control. Setting to zero does not perform
P-control.
C606: Integral Time (Sec)
This parameter is used to set the integral time for the I-control. Setting to maximum value does not
perform I-control.
C607: Derivative Gain
This parameter is used to set the derivative gain for the D-control. Setting to zero does not perform D-
control.
C608: PID deviation Upper Limit (%)
6
This is the upper limit for the PID output deviation. If the programmable sequence output PID Up
Limit is selected, the output will be ON, when the PID output reaches to this level.
C609: PID deviation Lower Limit (%)
This is the lower limit for the PID output deviation. If the programmable sequence output PID Lo Limit
is selected, the output will be ON, when the PID output reaches to this level.
C610: PID Offset Adjustment (%)
Sets offset for the output after PID control.
C611: PID Reference Setting (%)
When Local is selected as PID reference, this parameter is used to set the PID reference using digital
operation panel. This parameter will not have any effect if other options are selected as reference.
C612: PID Display Scale - Max
Use this parameter to scale the PID signals in terms of process parameters. This is used only for the
display purpose and will not have any effect on the operation. Unit display as per C614.
Set this to the max value of the process parameter feedback sensor and will correspond to 10V.
C613: PID Display Scale - Min
Use this parameter to scale the PID signals in terms of process parameters. This is used only for the
display purpose and will not have any effect on the operation. Unit display as per C614.
Set this to the min value of the process parameter feedback sensor and will correspond to 0V.
C614: PID Display Unit Selection
Select appropriate unit for the process variable.
