■ Overview
SIMATIC S7-300
Function modules
FM 354 positioning module
• Positioning module for servo mo tors in machines with high
clock pulse rates
• Can be used for point-to-poi nt positioning tasks and for
complex traversing patterns
Note:
SIMODRIVE Sensor/Motion Connect 500 feature positionmeasuring
systems and preassembled connecting cables for
counting and positioning functions.
