WithP control, only an offset between the target and feedback remains.n I ControlThe output of I control is the integral of the deviation. It minimizes the offset between target and feedback value that typicallyremains when pure P control is used. The integral time (I time) constant determines how fast the offset is eliminated.n D ControlD control predicts the deviation signal by multiplying its derivative (slope of the deviation) with a time constant, then addsthis value to the PID input. This way the D portion of a PID controller provides a braking action to the controller response andcan reduce the tendency to oscillate and overshoot.D control tends to amplify noise on the deviation signal, which can result in control instability. Only use D control whenabsolutely necessary.n PID OperationTo better demonstrate PID functionality, Figure 1.15 illustrates the PID output when the PID input (deviation) is at a constantlevel.1.2 b: ApplicationYASKAWA ELECTRIC SIEP C710636 10C Z1000U HVAC MATRIX Drive Programming Manual 311 Parameter Details
