Set Proportional (kP)

In a PID (Proportional-Integral-Derivative) controller, the "P" stands for Proportional.

UI Setting​

  • Navigate to the PID menu section from the Main Menu
  • Navigate to the Proportional menu
  • Use the rotary knob to adjust the P value

Usage Definition​

The Proportional component of the PID controller generates an output signal based on the difference between the desired setpoint and the current process variable. The P value, also known as the proportional gain, determines the strength of this response to the error signal.

Essentially, the P value dictates how aggressively the controller acts to reduce the error between the setpoint and the actual process variable. A higher P value means a stronger response to errors, potentially leading to quicker correction but also potentially increasing the risk of overshooting or oscillations in the system. Conversely, a lower P value might result in slower response times but could provide more stable control.

So, adjusting the P value allows operators to fine-tune the controller's behavior to achieve the desired balance between responsiveness and stability in the controlled system.
