A PID, Proportional-Integral-Derivative, controller calculates and minimizes the difference between a desired setpoint and a measured process variable by adjusting the system's control variable, ensuring precise and stable operation.

In previous lessons you learned to control a PowerFlex 525 drive and read IO-Link encoder data with MicroLogix PLC. You'll setup up a PID instruction in RSLogix 500, and addressing common pitfalls like data type mismatches and PID parameter configuration, moving towards a functional motor speed control loop.
