The Movifit FDC decentralised field controller from SEW-Eurodrive enables the construction of modular and flexible materials handling systems. Together with the Movigear mechatronic drive system and SEW’s Single Line Network Installation, energy saving, easy to install drive solutions can be implemented. Standardised function modules can be controlled via Profinet or Ethernet/IP and allow for easy diagnostics and maintenance, in addition to their short startup phase and quick reaction times.
Complex functions, easy use
Application solutions that can be user programmed and configured as required are one of the strengths of the Movifit FDC field device controller. It comes in a parameterisable variant with preconfigured application solutions for all types of materials handling technology or in an IEC 61131-programmable version for customer specific solutions. The application software runs on the controller, and data sets are saved there as well. Engineering access to the device is accomplished using USB or Industrial Ethernet. For system control, the controller has openings on top for all fieldbuses and has interfaces for the Ethernet protocols Profinet IO, Modbus TCP and Ethernet/IP. The individual axes are connected to the controller via a system bus on the input side.
Only one line needed
The Single Line Network Installation (SNI) technology from SEW has the significant advantage that instead of a 400 V supply system and communication bus, only one line is needed. This is used to daisychain all Movigear SNI drives. The communication for the SNI is modulated onto the power cable, which reduces time and effort needed for cabling and startup. This bus also provides good diagnostic options.
Dynamic applications
The CAN-based SBus system bus from SEW-Eurodrive can be used for especially dynamic applications. It combines the controller with the Movigear SBus mechatronic drives. This provides short reaction times and access to complex technology functions, for instance an electronic cam. Up to 10 participants can be connected to the SNI, and further ones via the SBus. In all, Movifit FDC can control a total of 16 drives.
Preconfigured application modules
Graphical parameterisation is made extremely easy with the help of preconfigured application modules that run on the controller. The three application modules – speed control, bus positioning and rapid/creep speed positioning – cover most of the processes that arise in intralogistics. The individual axes are selected and configured using the software. Only the DIP switches need to be set on the mechatronic drives. An SD card in the control saves all the drive data. If a Movigear is replaced in the course of servicing, the parameter set is automatically reloaded to the drive. Then a mechanic can proceed with replacing the device without any special programming knowledge.
The application configurator allows for easy and quick function diagnostics through a display with traffic light colours. Using the graphical diagnostics, the drive system can be tested and easily started up, even without a higher-level controller. This makes even complex functions easy to use.
The same application software can also be used for startup, PLC control and data storage for other SEW drive systems, for example a control cabinet installation with the Movitrac frequency inverter. Customers can also mix installation topologies regardless of their preferred topology. Movifit FDC is the flexible and economical controller solution for decentralised drive systems.
Precise detection of complex rotational movements Beckhoff Automation
Electrical switching & drive systems & components
The EP3751-0260 EtherCAT Box module by Beckhoff connects an acceleration sensor with an inertial measurement unit - a gyroscope. This provides accurate detection of acceleration and rotational motion in addition to shock, vibration and tilt measurement, both as preprocessed values and as raw sensor data.
