■ Overview
SIMATIC S7-300
Function modules
FM 357-2 positioning module
• Path and positioning control for in telligent motion control of up
to 4 axes
• Covers a wide spectrum from independent individual positioning
axes through to interpolatory multi-axis continuous-path
control
• For the control of stepper mo tors and controlled servo-drive
axes
• User-friendly startup through easy-to-use parameterization
tool
• Interface for SIMODRIVE 611U and MASTERDRIVES MC via
the isochronous PROFIBUS (not for FM 357-2H in combination
with HT6)
4
Note:
SIMODRIVE Sensor/Motion Connect 500 feature positionmeasuring
systems and preassembled connecting cables for
counting and positioning functions.
