PID Paras
Proportional Gain Dimensionless value used by PID block algorithm to calculate a
block output.
Integral Time The integral time constant, in second per repeat.
Derivative Time The derivative time constant, in seconds.
FF Gain The gain applied to an optional feed-forward input before it is
added to the calculated control output.
FF Value (Manual
Reset Bias)
The optional feed-forward value.
Limits
Set Point High Limit The highest value allowed for the PID set point.
Set Point Low Limit The lowest value allowed for the PID set point.
Output High Limit The limit for the maximum PID output value.
Output Low Limit The limit for the minimum PID output value.
