For controlling rapid traverse/creep speed drives

Description

The FM 351 is a module for adjusting and positioning mechanical axes based on the rapid traverse/creep speed principle. With this module, two axes can be positioned independently of one another. The axes to be positioned may be linear axes with limited traversing range and continuously rotating rotary axes. Incremental encoders and SSI encoders can be used for position decoding. The FM 351 is used in the SIMATIC S7-300, C7 and in the ET 200M on S7-masters as well as with WinAC Basis and WinAC Slot 41x.

Solves position or time-dependent tasks

Description

The FM 352 electronic cam controller is a 1-channel module for solving position- or time-dependent tasks.
They are far superior to mechanical cam controllers, particularly thanks to their high level of flexibility.

Advantages

Either an incremental encoder, an SSI encoder or a 24 V initiator can be connected.
32 cam tracks can be read from the automation system's CPU.
13 cam tracks can be output directly over integrated digital outputs
The module can be quickly adapted to the relevant cam control application by means of parameters.
The FM 352 off-loads the CPU thanks to autonomous, actual value-dependent setting and resetting of electronic cams
The FM 352 is used in the SIMATIC S7-300, C7 and ET 200M on S7 masters

For stepper motor control

Description

The FM 353 is a positioning module for controlling stepper motors. It can perform many functions for solving a wide variety of positioning tasks, and offers a high level of precision, dynamic response, and user-friendliness.
In contrast to modules which control servomotors, the FM 353 requires no position decoding system

It can be used in all low-load positioning tasks and where there are no major load fluctuations. When these prerequisites are fulfilled, virtually the same degree of accuracy can be achieved with the FM 353 and stepper motors (µm-range) as with servomotors.

The FM 353 is used in the SIMATIC S7-300, C7 and ET 200M on S7 masters. Operation with WinAC Slot 41x is possible.

Description

Ultra-high-speed binary logic operations and the fastest possible path-dependent switching operations combined with exceptionally little jitter - Those are the strengths of the SIMATIC FM 352-5 application module.
With a cycle time of only 1 µs, it is clearly superior to any conventional PLC CPU.
Whether you want to increase the machine cycles, produce products of the highest quality, or prevent machine or tool damage - the FM 352-5 is exactly the right choice.

Advantages

Ultra-high-speed switching and logic operations
More productivity, less waste, fewer downtimes
FastConnect I/O terminals right on board:
12 digital inputs
8 digital outputs
1 position encoder (SSI, 5V and 24V incremental encoders)
Preprogrammed standard blocks shorten engineering time
Freely programmable in LAD and CSF with limited operations set using established standard STEP 7 software
For universal use in different control system configurations
Available in two different versions with current-sourcing or current-sinking outputs

For servomotor control

Description

The FM 354 is a positioning module for position control with servomotors. It is suitable for precise position control in the face of load fluctuations or high dynamic response.
The FM 354 can be used for simple point-to-point positioning as well as for complex velocity profiles with the very highest demands on dynamic response, precision and speed, and is thus the ideal solution for positioning tasks with high clock-pulse rates both in mini controls and in distributed configurations directly on the machine.
The FM 354 is used in the SIMATIC S7-300, C7 and ET 200M on S7 masters as well as with WinAC Slot41x.
