SIMATIC S7-400
Function modules
FM 453 positioning module
6/83
Siemens ST 70 · 2013
■
Overview
• Positioning module for servo and/or stepper motors in
machines with high clock-pulse rates
• Can be used for simple point-to-point positioning and for
complex traversing profiles
• Up to 3 independent motors can be controlled
Note:
We offer position measuring systems and preassembled
connecting cables for counting and positioning functions under
SIMODRIVE Sensor or Motion Connect 500.
