Festo – CMSX-...-C-U-F1-... – 1506a English

Control parameters (PID--P, PID--D)

These parameters influence the control behaviour of the device. This permits adapting the positioning

speed and the control behaviour to the respective requirements.

The I-part of the PID controller cannot be changed by the user. It is preset at the factory to a value ap­

propriate for the function.

But incorrectly set parameters can result in overswings or permanent oscillations around the setpoint

position. Small drives react to this more sensitively than large drives.

PID--P

The parameter PID--P influences the P-part of the PID-controller.

– Increasing the value increases the setpoint specification change in the case of a deviation. A

P-share that is too high results in overswings.

– Reduction in the value causes a reduction in the setpoint specification change in the case of a devi­

ation. A P-share that is too small results in slower regulation.

PID--D

The parameter PID--D influences the D-part of the PID-controller.

– Increasing the value changes the setpoint specification change less strongly with the same change

in speed of the deviation. Regulation becomes more sluggish.

– Reducing the value changes the setpoint specification change more strongly with the same change

in speed of the deviation. Regulation becomes more dynamic.
