Function modules
FM 452 cam controller
6/81
Siemens ST 70 · 2013
■
Overview
• Very high speed electronic cam controller
• Low-cost alternative to mechanical cam controllers
• 32 cam tracks, 16 onboard digital outputs for direct output of
actions
• Incremental or synchronous-serial position feedback
Note:
We offer position measuring systems and preassembled
connecting cables for counting and positioning functions under
SIMODRIVE Sensor or Motion Connect 500.
