1 FM POSITIONING MODULE Function FM with FM 357L system firmware 4 measuring circuits for the connection of position-controlled servo axes/stepper drives or external master axis Relationship of axes: Linear, circular interpolation, independent single axes Axis synchronization via coupled motion or curve tables (electronic cam) also with external master Motion control with programmable acceleration and jerk limitation Transformable coordinate systems Operating modes: Jog, incremental, reference-point approach, MDI (Manual Data Input), automatic, automatic single-block Limit switching signals (cam controller) Special emergency stop routines with high-speed restart Program-controlled motion output from the motion program, M instructions Parameterizable programs via user variables Programming in accordance with DIN with high-level language elements (loops, conditions) Data backup to memory card (optional) Multichannel capability (up to 4 channels can be defined in any combination, 1 channel in the case of FM 357-2H) Page 1210 Mar 2008 Siemens ITS

2 FM with FM 357 LX system firmware As for FM with FM 357L system software, plus: Spline interpolation (A-, B-, C spline) for definition of movements via interpolation points High-value gantry functions with rigid compensation control Flexible synchro actions (expanded interrupt routines) Probe analysis without time-delay Programmable overlay of oscillation movement Path-speed-dependent variable control Programmable travel against fixed stop 3 D protection zones FM with FM 357 Handling system firmware As for FM with FM 357LX system software, plus: Coordinate transformation for jointed-arm, Scara and gantry systems with up to 4 axes Teach-in functions with the HT6 handheld terminal Page 1211 Mar 2008 Siemens ITS

3 Mode of operation Preparatory steps Load the firmware and parameterization software supplied separately Wizard-supported comparison of machine data with the configuring software integrated in STEP 7 Generation of traversing programs: Generation with the editor of the parameterization software according to DIN Implementation of coordination and sequence control functions in the STEP 7 user program on the CPU. Standard function blocks simplify this task. Positioning and continuous-path control The FM controls the axes independently. Positioning tasks are started via the OP or higher-level programmable controller Human machine interface Using any SIMATIC HMI components; SIMATIC OP7 and OP17 also support direct communication with the FM Direct variable access is also possible with ProTool Version 6 and Windows-CE-based operator panels from TP170B upwards.
