For control of rapid traverse/creep speed drives

Description

The FM 451 is a positioning module for adjusting and positioning mechanical drives on the basis of the rapid traverse/creep speed principle.
The FM 451 is used in the SIMATIC S7-400. The module makes it possible to position three axes independently of one another. The axes in question may be linear axes with limited traversing range or continuously rotating rotary axes.
Incremental encoders and SSI encoders can be used for position decoding.

 

For position-dependent or time-dependent tasks

Description

Cam controller FM 452 for SIMATIC S7-400

The FM 452 electronic cam controller is a 1-channel module for the solution of position-dependent or time-dependent tasks.
The FM 452 is far superior to mechanical cam controllers, due particularly to its high level of flexibility.
An incremental encoder, an SSI encoder or a 24 V initiator can be connected to the module.

Advantages

  • 32 cam tracks can be read by the automation system's CPU    

  • 16 cam tracks can be output directly over integrated digital outputs

  • The module can be quickly adapted to the relevant cam control application by assigning appropriate parameters.

  • The module off-loads the CPU thanks to autonomous, actual value-dependent setting and resetting of electronic cams.

 
 

The universal solution for closed-loop control

Description

The FM 455 controller module has 16 channels, and is suitable for universal use, e.g. for temperature, pressure, flow and level control.The FM 455 controller module for the SIMATIC S7-400 can also be used in PCS7 systems.

It offers:

  • a variety of preprogrammed control structures,    

  • a self-optimization function with which controllers can be quickly and easily optimized, and   

  • a backup function for problem-free operation in the event of a CPU stop/failure.


The module is available in two versions for controlling different actuators:     

  • FM 455 C as continuous-action controller for analog actuators

  • FM 455 S as step-action or pulse-action controller for the control of actuators via digital outputs

 

For control of servomotors and stepper motors

Description

The 3-channel FM 453 positioning module is suitable for a broad spectrum of positioning tasks with stepper and servo motors.
Rotary and linear axes can be traversed absolutely or relatively.
The module can be used for simple point-to-point positioning tasks as well as for complex traverse profiles with the highest demands for dynamic response, accuracy, and velocity through to multi-axis applications.
Application examples include positioning infeed axes, positioning axes, setup axes, operating axes, production axes, and transport axes.

Autonomous positioning of the stepper and servo motors takes the load off the CPU of the automation system.
FM STEPDRIVE and SIMOSTEP stepper motors perfectly complement stepper motor axes. The same applies for servo motor axes with SIMODRIVE 611 Universal or MASTERDRIVES MC/VC and 1FT6-/1FK6-/1FK7 servo motors.   

The main functions performed by stepper and servo motors include:

  • Automatic mode:     
    Execution of complex positioning profiles (traverse programs) continuously or also step by step. The traverse programs can be loaded during operation

  • MDI/MDI on-the-fly   

  • Jog/setup

 

High-End Application Module FM 458-1 DP

Description

Within the SIMATIC S7-400, the enhanced application module FM 458-1 DP is setting new standards. This intelligent module combines powerful arithmetic operations ability, high processing speed, precision and flexibility. These are the features required to solve a wide range of processing tasks universally even with extremely high throughput rates

For you this means: even more flexibility and economic viability in implementing sophisticated PLC, motion control and processing tasks.

Communication
Communication takes place over the PROFIBUS DP interface on the FM 458-1 DP. This offers the following characteristics:

  • Constant bus cycle time, i.e. the PROFIBUS DP cycle is always precisely the same length.

  • Isochronous, i.e. the CPU, I/O and user program are synchronized with the PROFIBUS cycle.

  • Slave-to-slave communication, i.e. the configured slaves can exchange data with each other directly without the need for any additional configuring work on the FM 458-1 DP.

  • Routing capability, i.e. all nodes are accessed over one interface, e.g. MPI (Multi-Point Interface) or PROFIBUS DP and optionally also Industrial Ethernet.

Up to 100 drives of the SIMOVERT Masterdrives series or SIMOREG series can be connected per ring over the highspeed, fiber-optic SIMOLINK connection.

Advantages

  • Integrated into SIMATIC S7-400 racks: Open-loop and closed-loop control and arithmetic operations

  • Software tools STEP 7/CFC and SFC are identical to the tools for SIMATIC S7

  • Sampling times from 100 µs for dynamic motion control and processing solutions.

  • Isochronous PROFIBUS DP - constant-time bus cycle with clock signal

  • Clock synchronism - CPUs/I/O and user programs are synchronized to common PROFIBUS clock

  • Routing, diagnostics and teleservice possible via a single interface

  • The I/O expansion EXM 438-1 provides extremely fast, synchronizable
    - Digital and analog inputs and outputs
    - Speed and absolute value encoder measurement

  • The EXM 448/EXM 448-1 communication expansions provide fast connection of drives including:
    - PROFIBUS DP, as master or slave (not isochronous/clock-synchronized)
    - SIMOLINK, the fast, powerful, clock-synchronized fiber-optic cable (installed in EXM 448-1)

Task  

Features

Counting/Measuring

Suitable for a wide range of different counting and measuring tasks with incremental or absolute value encoders up to a maximum of 2.5 MHz

Cam Controls

16 digital outputs as cam tracks (displacement or time cams). Each track can be individually adapted to the task with a delay or overrun. Dynamic delay, dynamic hysteresis 

Closed-loop Control

Controller structures/types are freely programmable, e.g. fixed value control, follow-on control, cascading control, ratio and mixer controls, continuous and override control, pressure, level and temperature control, hydraulic control, drive control

Motion Control

Open/closed-loop controlled positioning of up to 16 individual axes as well as multi-axis applications over PROFIBUS DP or SIMOLINK

Assessment Services new

Assessment Services

Safety Assessments

Safety Assessments help you comply with current and emerging standards by providing consulting services for safety critical controls. Our solutions can help reduce lost-time accidents, improve workplace safety and improve employee morale, which will ultimately result in increased productivity.

These exception-based assessments are a quick and inexpensive way to audit a machine /work cell to determine the obvious points of operation and power transmission hazards. The result of the hazard assessment is a concise report that identifies the location of each observed hazard and provides a rough budgetary estimate for safeguarding. The hazard assessment will also provide:

  • General recommendations on how to guard a machine/work cell
  • A prioritization plan for your machine safeguarding project when many unique machines need to be evaluated and upgraded
  • The unbiased, third party opinion of a machine safety consultant with the required knowledge of relevant safety standards, best practices and current safeguarding technology.
