Pneumatic actuator for servo positioning and force control

Festo's DDLI servo-pneumatic actuator delivers precise dynamic movement of large loads for OEMs and can regulate feed forces on the fly.


Festo's DDLI servo-pneumatic actuator delivers precise dynamic movement of large loads for OEMs and can regulate feed forces on the fly. Courtesy: FestoFesto's DDLI servo-pneumatic actuator with integrated position feedback is designed to offers original equipment manufacturers (OEMs) fast, controlled positioning and the capability to regulate feed forces on the fly. The DDLI is useful for positioning a diverter on a conveyor, opening and closing large machine doors, clamping, and more.

When used with the Festo CPX-CMAX servo-pneumatic controller, the DDLI can be operated like an electric servo drive to perform position and force tasks. Use the integrated record set table to predefine position and force tasks in the CMAX controller. Or send position and force directly from the PLC to the CMAX controller and modify movements on the fly.

The DDLI is well-suited for precise dynamic movement of large loads. When used with the Festo CPX-CMPX soft stop module, DDLI eliminates impacts at the end position and achieves faster cycle times as a result. 

The actuator has an IP67 protection rating, which makes it suitable for wet and dirty environments. Modules can be quickly exchanged and expanded without altering wiring. OEMs can configure, commission, and operate the DDLI via fieldbus from within the PLC environment.
