Siemens FM357-2 S7-300 plcmodule 6ES7357-4AH01-AE0
Bought the module and the firmware for £1844 used for three months
* Path and positioning control for intelligent 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 motors 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)
SIMODRIVE Sensor/Motion Connect 500 feature position-measuring systems and preassembled connecting cables for counting and positioning functions.
Additional information is available in the Internet under:
The FM 357-2 is a continuous-path and positioning control for intelligent motion control of up to 4 axes. It supports an extensive range of applications from independent individual positioning axes to interpolatory multi-axis continuous-path control.
* Metal and woodworking, plastics and stoneworking
* Textiles and packaging technology
* Position-controlled servo-drive axes
For operation of the FM 357-2, the FM 357-2L, FM 357-2LX or FM 357-2H system software is essential.
In addition to the FM 357-2, the positioning and continuous-path control contains the following essential components:
* S7-300 CPU, CPU 314C upwards is recommended
* For sequential control and coordination of:
Start/stop of traversing motion, specification of target positions, selection of traversing programs, transfer of parameters; three FM 357-2 modules can be connected per CPU (only one in the case of FM 357-2H)
* for user-friendly parameterization and startup
* for operator control and monitoring of the machine
The following systems are particularly suitable for axis control:
* SIMODRIVE 611A with 1FT5 motors as analog drive system
* SIMODRIVE 611 Universal with 1FK6/1FT6 motors as digital drive system
* FM STEPDRIVE with SIMOSTEP motors for stepper motor axes
FM 357-2 with FM 357L system firmware
* 4 measuring circuits for the connection of position-controlled servo axes/stepper drives or external master axis
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
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,
* Parameterizable programs via user variables
* Programming in accordance with DIN 66025 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)
FM 357-2 with FM 357 LX system firmware
As for FM 357-2 with FM 357L system software,
* 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
As for FM 357-2 with FM 357LX system software,
* Coordinate transformation for jointed-arm, Scara and gantry systems with up to 4 axes
* Teach-in functions with the HT6 handheld terminal
* 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 66025
* 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 357-2 controls the axes independently. Positioning tasks are started via the OP or higher-level programmable controller
* Using any SIMATIC HMI components;
SIMATIC OP7 and OP17 also support direct communication with the FM 357-2. Direct variable access is also possible with ProTool Version 6 and Windows-CE-based operator panels from TP170B upwards.
