Programmable Cam Functionality
The 6FM1715-3AA20 creates cam profiles using the actual encoder position values. Each cam track can define multiple on and off positions. The module compares the current position against stored cam profiles for precise output switching.
High-Speed Position Processing
The module evaluates encoder counts at high speed for accurate cam switching. It responds to position changes without CPU intervention. This real-time performance suits high-speed packaging and cutting applications.
System Integration and Configuration
Users configure cam parameters through STEP 5 software. The module receives power and communicates via the S5 backplane. Engineers can store multiple cam profiles and switch between them.
Industrial Applications
The 6FM1715-3AA20 excels in packaging machines, press controls, and rotary indexing tables. It replaces mechanical cams for greater flexibility and reduced wear. Consequently, production changeovers become quicker and easier.
