Evaluation Unit monitors joining and press-fit processes.

Press Release Summary:




Designed for electromechanical NC joining systems, DMF-P A310 Universal Type 4740A Force-Displacement Evaluation Unit features integral EtherNet/IP master, which replaces 4 cables and allows servo controller to be operated and controlled directly by DMF-P A310 unit. System monitors joining and press-fit processes with aid of adjustable windows, making it possible to keep track of parameters such as fitting forces, end points, or overloads in automated joining processes.



Original Press Release:



New Force-Displacement Evaluation Unit DMF-P A310 Universal Type 4740... for NC Joining Modules with Numerous Practical Advantages



With Kistler's DMF-P A310 Universal Type 4740A... a new force-displacement evaluation
unit for electromechanical NC joining systems is introduced. It is a development of the
widespread DMF-P A300 NCF Type 4734A..., which has proven uniquely effective in
complex industrial joining processes. The operating concept with clear, user-friendly
guidance is along the same lines as the previously marketed force-displacement unit DMF-P A300 NCF.

The enhancements have focused on optimizing and speeding up system commissioning for
faster installation at lower cost. The integral EtherNet/IP master replaces four cables and significantly reduces cabling and installation work. Its functionality allows the servo controller to be operated and controlled directly by the DMF-P A310 Universal. Faster data transmission even at program changeovers shortens cycle times. During commissioning the system can still be run without the master control system being fully functional. Integral control allows quick and easy setting up for all common control systems without any special function block. Further optional fieldbuses such as EtherNet/IP, ProfiNet IO and DeviceNet are available for this purpose. The system comes with a Profibus interface as standard.

Connection of an external displacement sensor is possible as an option. The DMF-P A310
Universal's sequence control offers "Automatic", "Move" and "Service" mode. The system monitors joining and press-fit processes with the aid of adjustable windows, and
makes it possible to keep track of parameters such as fitting forces, end points or overloads in automated joining processes. The new system also has evaluation windows for functions such as break-point, for example for detecting and stopping motion when a retaining ring snaps into place. It provides the station control system with the result of the evaluation in the form of, for example, a OK or NOK signal, measurements and set points.

Along with a certified Q-DAS interface, various protocols such as I.-P.M., .csv files with set points and actual values including part number with curve are available for documentation.

Kistler provides the system with remote connectivity via Ethernet to support customers' use of the DMF-P series of force-displacement evaluation units.
