With the scalable safety products from Eckelmann and Ferrocontrol and security solutions fully integrated in the automation, mechanical engineers manage to combine safety, availability and productivity. Safe, efficient and comfortable!

Safety Engineering

The range of safety products is perfectly tuned to Eckelmann’s and Ferrocontrol’s control and drive technology and makes for integrated security solutions that are seamlessly tailored to the automation technology, from programmable safety controllers with finished function blocks for the rapid development of a safety logic to high-performance and easy-to-configure drive-integrated safety functions, TÜV-certified up to SIL 3 (Safety Integrity Level in accordance with EN IEC 62061) or PL e (Performance Level according to EN ISO 13849-1).

SISTEMA Library

Before their application in the plant, safety functions must demonstrate that the achieved safety level at least satisfies the specifications. A tool suitable for this purpose is the manufacturer-independent SISTEMA programme developed by the Institute for Occupational Safety IFA.

For the security modules from Eckelmann and Ferrocontrol, a library is available for download that can be opened in SISTEMA. It provides the performance indicators required for the proof.

E°SLC 204: Safety Controller

The E°SLC safety module from Eckelmann can be used with little effort to monitor a variety of safety devices on machines and equipment; whether emergency stop switches, light barriers, laser scanners, two-hand operation, jog mode, door contacts or light curtains with muting function. The safety module makes the monitoring of individual sensors via safety relay obsolete. Thanks to the large number of predefined special function blocks, modern safety concepts can be easily implemented.

The safety functions can be quickly created on a PC using the E°Tools SLC graphical configurator. A safety logic system can be developed from available function blocks via drag & drop, simulation and commissioning can be implemented with the same development tool. The configuration data are easily transferred via USB.

The E°SLC safety module has 20 safe inputs and 4 safe outputs; using safe expansion I/O modules, it can, where necessary, be expanded up to 100 inputs and 44 outputs (up to 8 safe inputs and 4 safe outputs per module, 4 ports can be switched as inputs or outputs, i.e. the module has either 8 inputs and 0 outputs or 4 inputs and 4 outputs).

Via CAN fieldbus coupler (CANopen™), the complete process image and the internal states of the safety module are comfortably transmitted to the superior control and operating level (maximum of 92, optionally pre-processed signals). The result is well-integrated and user-friendly security solutions with advanced diagnostic functions.

E°Darc SCM: Drive-Integrated Safety Functions

The E°Darc SCM safety controller module makes it easier for mechanical engineers to implement modern drive-side safety concepts. For this purpose, they can rely on a wide range of certified security functions, e. g. STO (Safe Torque Off), SLP (Safely-Limited Position) or SLS (Safely-Limited Speed) (see graph).

All Eckelmann components are closely integrated to work together: the application on the non-safe PLC controls the drive controllers via field buses such as CAN or sercos. Safety features requested by a safe sensor or operating mode selector are handled by the safe control of the E°Darc SCM or an additional E°SLC safety module which, via bus coupler, transmits the change to a different operating mode to the non-safe PLC, and simultaneously activates safety functions in the E°Darc safety controller module. The E°Darc SCM monitors the parameterised limits of the safety features active and performs the parameterised safety responses, if necessary.

The wide variety of safety features make for a differentiated system responsiveness. While, in the event of an error, conventional solutions only offer STO, i. e. uncontrolled coasting to a stop, the E°Darc SCM also allows for operating the system at a reduced speed and, thus, for the continued production or the controlled shutdown of an axis. This is important for all axes that need to support load torque at standstill, such as hanging axes.

  • TÜV-certified safety functions up to SIL 3 or PL e
  • Capable of being freely configured and combined: 5 safe inputs and 2 safe outputs
  • User-friendly installation on safe editor under E°Tools Light
  • Response times of up to 20 ms
  • Differentiated responsiveness to security-related events and operation modes
  • Easy-to-implement safety chains for connected axis packages of a machine
  • High availability and robustness due to safety encoders directly mounted on the engine
  • Easy transfer of safe parameter set via SD card

Safe Standstill Monitor Integrated

Drilling spindles as in this rod machining centre are a potential application area for safe standstill monitors.

The E°Darc C drive control system is equipped with a safe standstill monitor that evaluates the encoder signals of high-frequency spindles. The system is designed to meet safety integrity level 2 (EN 62061) or performance level d (DIN EN ISO 13849-1). Engines with a speed of up to 40,000 rpm can be monitored via plug-in modules that are integrated in the controller. The motor standstill is displayed via safe module outputs. Compared to external solutions this saves cost as well as space in the switch cabinet. The standstill monitor is integrated in the safety technology of the machine which actuates, for example, the door locking device.
