FM 357 - New Function Module for 4-axes Control
Concerns products with the Catalog No.'s: 6ES6 357-4AH00-0AE0 FM 357 4-axes controller 6ES6 357-4AH00-3AE0 FM 357 firmware, single license 6ES6 357-4AH00-3AE6 FM 357 firmware, runtime license 6ES6 357-4AH00-7AG0 FM 357 configuration package, German 6ES6 357-4AH00-7BG0 FM 357 configuration package, English 6ES6 357-4AH00-7CG0 FM 357 configuration package, French 6ES6 357-4AH00-7EG0 FM 357 configuration package, Italian The FM 357 positioning and continuous path controller for up to 4 interpo- lating axes is now available. Both linear and rotary axes with servo drives or stepper motors can be implemented (mixed operation is also possible). _Hardware features:_ - Up to 4 axes can be connected. - Incremental position encoders (RS 422) or SSI encoders; can be used for position monitoring in stepper motor mode. - +/-10 V analog interface to servo motors. - Clock signal for stepper drives. - 4 high-speed inputs, e.g. for reference point cam or high-speed synchro- nization and 2 measuring inputs for cutting "on the fly", for instance. - More high-speed I/Os are possible in the local bus segment. _NC functionality:_ The module is based on the FM-NC module and was modified for the require- ments of general machines. The FM 357 has all the functions a user expects from a modern 4-axes continuous path controller, e.g.: - Interpolation of all axes (linear, rotary, helical curve, spline). - Simple synchronous operation (coupled motion). - Programmable acceleration and rate-of-change limiting. - M functions as well as setting and reading of I/O signals. - Traversing path programming acc. to DIN 66025 with additional high-level language elements. _Parameterization:_ The configuration package for parameterization, commissioning and testing contains: - Parameterization and commissioning tool with commissioning assistant integrated in the SIMATIC Manager. - Standard software blocks for the connection of the FM 357 to the S7 CPU. - Manual in paperback form. - Screen forms for the OP 17. _HMI:_ The full range of S7 OPs can be used for HMI functions, from the OP 3 to the OP 37. OP 7 and OP 17 additionally offer an extended direct access to the NC data via a variables selector. _Software prerequisites:_ - Configuration package and STEP 7 V3.1. - ProTool V3.0 if the extended direct access by means of a SIMATIC OP is required. Your SIMATIC contact at your local Siemens office will answer any more questions you may have. -------------------------------
