The DO 3001 uses digital PID (Proportional, Integral, Derivative) control. Section 6.3 covers "Optimizing the Control Loop."
– The controller continuously compares actual position (sensor signal) to a stored reference (setpoint) and adjusts the actuator to minimize error. PID parameters (proportional gain, integral time) are adjustable via hidden parameter menu.

Below is a detailed feature looking into the functionality, design, and operational significance of the Do 3001 manual and the device it describes.
In the world of industrial web processing—printing, coating, laminating, nonwovens, paper, film, foil, and textiles—precise lateral web alignment is non-negotiable. Erhardt+Leimer (E+L) has long been a benchmark name in web guiding systems. Among their legacy and transitionary control units, the represents a specific generation of digital/web guide controllers that bridged purely analog systems and fully networked, HMI-driven modern platforms. This essay explores the typical purpose, operational logic, interface, and practical use of the DO 3001 as would be described in its original manual. The DO 3001 uses digital PID (Proportional, Integral,
