WF 705 · POSITION MEASURING MODULE
Twelve-axis SSI absolute-encoder position acquisition for SIMATIC S5 and adapted S7-400 systems.
Siemens 6FM1705-3AA00 is the WF 705 position measuring module for acquiring absolute position values from SSI encoders. Siemens documents independent measurement for up to twelve axes using synchronous serial data transmission, with RS422 signaling at 1 Mbit/s for cable lengths up to 25 m or 125 Kbit/s up to 120 m. The module can operate as an I/O module in SIMATIC S5 systems and, through an adapter capsule, in SIMATIC S7-400. Replacement planning should verify the complete suffix, encoder coding and data format, baud rate, cable length, address assignment, direct or distributed encoder connection, rack position, adapter requirements and application software.
