Siemens PLC Expansion Module for Use with S7-300 Series, Digital, Digital

The FM 351 positioning module is used for controlled positioning with rapid traverse/creep speed drives in the S7-300 automation system. The module has 2 independent channels and, thus, controls one rotary axis or one linear axis at a time. The module supports one incremental encoder or one absolute encoder (SSI) for each channel. You can operate several FM 351 positioning modules simultaneously. It is also possible to combine with other FM / CP modules. A typical application would be combining with an FM 352 electronic cam controller (746-6696).

Two axis with axis types including: linear axis & rotary axis
Four digital outputs per axis & four digital inputs per axis
Typical drives / motors: standard motor - relay controlled, standard motor on frequency inverter (e.g., micromaster) & asynchronous motor on power section with vector control
Position measuring systems include: incremental encoder 5 V, symmetrical, Incremental encoder 24 V, asymmetrical & SSI absolute encoder
Monitoring functions include: monitoring the operating range by means of software limit switches, standstill monitoring, encoder monitoring, monitoring for axis movement and target approach
System environment comprises of: centralised application, SIMATIC S7-300 from CPU 314 (recommendation: depends on user memory requirement of the application) & distributed use with ET 200M
System integration comprising of: module exchange possible without PG & Teleservice possible
