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 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
