Kistler DMF-P A300 NCF Force Displacement Evaluation Unit

The Kistler DMF-P A300 NCF Type 4734AWDY2X400S1 is a single-channel force-displacement measurement and monitoring system for assembly and press-fit processes. This evaluation unit is designed for applications requiring independent monitoring of joining processes, particularly in electromechanical NC joining systems. The DMF-P A300 NCF has proven uniquely effective in complex industrial joining operations across multiple production lines.

System Overview

The DMF-P A300 NCF monitors assembly and press-fit processes with the aid of adjustable evaluation windows. It tracks critical parameters including fitting forces, end points, and overload conditions during automated joining operations. The system provides the station control system with evaluation results in the form of OK or NOK signals, along with measurement values and setpoints. An optional external displacement sensor connection is available for expanded measurement capabilities.

Functional Capabilities

The system features sequence control offering Automatic, Move, and Service operating modes. Evaluation windows support functions such as break-point detection, which identifies when a retaining ring snaps into place and can stop motion accordingly. The DMF-P A300 NCF includes an integral Profibus interface as standard. Optional fieldbus protocols include EtherNet/IP, ProfiNet IO, and DeviceNet for integration into higher-level control systems.

Data Management and Documentation

A certified Q-DAS interface is provided for statistical process control and quality documentation. Various data protocols are available including I-P-M format and CSV files containing setpoints and actual values complete with part number and curve data. This documentation capability supports traceability requirements and quality assurance standards in regulated manufacturing environments.

Connectivity and Remote Access

Kistler provides remote connectivity via Ethernet to support customers using the DMF-P series of force-displacement evaluation units. The integral EtherNet/IP master reduces cabling requirements by replacing multiple discrete connections, significantly minimizing installation work and reducing system complexity. This architecture allows the servo controller to be operated and controlled directly by the force-displacement unit.

Commissioning and Operation

The operating concept features clear, user-friendly guidance for fast system commissioning and installation. During commissioning, the system can be operated without the master control system being fully functional, enabling parallel development and reducing startup time. Integral control allows quick configuration for all common control systems without requiring special function blocks, making the unit adaptable to various automation environments.
