The DO 3001‑AG 9 pair is used on unwinders, rewinders, and large pivoting frames for web guiding. For a pivoting‑frame system (ELGUIDER), the web is deflected four times by 90°, and the pivot point lies on the infeed plane.
The AG 9 is noteworthy for its brushless motor, which is wear-free and maintenance-free. It features an integrated absolute encoder, eliminating the need for a reference run on commissioning and retaining position information even after a power failure. The system also boasts Ethernet networking with response times of just 1 ms and an actuating speed of up to 60 mm/s, ensuring maximum actuating dynamics for precise web control.
