Mayr Power Transmission: Brake Technology 4.0 Brake technology 4.0 by Mayr Power Transmission stands for monitoring modules of the latest generation: The modules such as the ROBAbrake-checker or ROBA-torqcontrol allow permanent brake monitoring and make the safety brakes fit for the challenges of the Industry 4.0. Firmly connected with the brake technology 4.0 concept are also a technologically leading friction system and consistently-observed safety principles. Together, these characteristics form the basis for reliable and safe brakes with extremely high performance density. They guarantee highest operational safety in more and more compact and high-performance machines and systems, and allow targeted, predictive maintenance. Eaton’s hydraulic hoses designed for tighter spaces, higher temperatures and abrasion Power management company Eaton has expanded its range of hydraulic hoses with the launch of the Dynamax EC881 hose series. The new EC881 series from Eaton is qualified for 1 million impulse cycles, five times more than the standard EN857 Type 2SC. This helps decrease maintenance costs, improves safety and minimizes downtime. Standard EN857 2SC size 8 hoses are only qualified to 130 mm radius, whilst EC881 offers a bend radius of 60 mm. This makes the new hose the ideal choice for installation in tight spaces. Featuring Dura – Tuff covers, the EC881 is 8 times more resistant to abrasion than conventional synthetic covered hoses, ultimately leading to less failures and improved machine up time. In extreme operating environments high velocity leads to high temperatures. The EC881 has been designed to offer temperature capabilities up to 126 °C, thus mitigating against the risk and ultimately controlling maintenance costs. Eaton engineers have focused on developing a next generation inner tube that has 3 times the life span capabilities when compared to the standard EN857 2SC. EC881’s high fatigue resistance and low compression set provides better sealing and leak free performance. PRODUCTS Rotational speed and directional sensor with PWM-signal from Rheintacho With a new rotational speed sensor from the FE series, Rheintacho presents a sensor ideally suitable for hydraulic drives used in construction and agricultural equipment. From the beginning of the design concept, the design took highly demanding working conditions into consideration. Having this in mind, the sensor achieved the IP67 and IP6K9K ratings. This means dirt, moisture and intensive cleaning methods are no problem for the sensor. The housing is made of a special brass alloy which ensures that the compressive strength of the measuring surface is high. The new sensor adds a rotational direction signal to the rotational speed signal. The electronic design with a pulse-width modulated signal (PWM) works with a current signal differing from the 1-channel and 2-channel version, on which the rotational direction information is transmitted through the differing pulse lengths. At the same time, this sensor also provides a signal with a constant amplitude independent from the rotational speed. It excels not only by detecting rotational speed and direction, but also provides additional diagnostic functions, e.g. downtime recognition, critical air gap and critical installation position. Control units of the fourth generation from STW Sensor-Technik Wiedemann (STW) showcases its fourth generation of controls for mobile applications. The ESX-4CS-GW is a freely programmable a communications gateway, it not only offers 6 CAN interfaces, but also a 4-port Ethernet switch, a LIN and a RS232 interface. With an additional 14 analog and digital inputs and outputs in the standard configuration, it is also able to take over small tasks for sensor-actuator management. For fast processing of the tasks, the fourth generation of the ESX control units feature the Infineon Aurix processor, which works with 300 MHz using three 32-bit TriCore processor as the so-called “Triple-TriCore”, each of which are independent from the other. Naturally the ESX-4CS-GW complies with the standards for conformity according to CE and E1 as well as the standards for the vehicle, agricultural and construction machine industry. The respective development environments for the fourth generation of control units are ‘codesys’ and openSYDE. With openSYDE, STW displays its framework and toolset for the implementation, analysis, maintenance and documentation of functions and programs in the control system for mobile machines.

Mitsubishi Electric’s AutomationML to reduce costs and shorten time to market Beckhoff’s integrated servo drive technology results in significant cost and space savings The new AMP8000 distributed servo drive system from Beckhoff integrates the servo drive directly into a servomotor in an ultra-compact design. By relocating the power electronics directly into the machine, space requirement inside of control cabinets is reduced to a single coupling module. Via EtherCAT P, providing EtherCAT signals and power with one cable, such a coupling module can control up to 5 distributed AMP8000 servo drives. With fewer and smaller cable routes to the motors, installation efforts are significantly reduced. Since the power module is conveniently located at the back end of the motor shaft, the attachment dimensions of the new distributed servo drives are identical to those of the proven standard AM8000 series servomotors. The only dimensional change is to the overall servomotor length, which is extended by approximately 7 cm. For the machine builder, this means that only a little additional space is needed at the motor end, and adjusting the overall motion control concept is easy without having to otherwise alter existing machine designs. Mitsubishi Electric has implemented the AutomationML interface within the integrated software suite for programming its own automation products. This represents an important step-change in the way complex equipment is designed, installed and maintained. Exchange of data between various engineering disciplines causes manual errors and is time consuming. Implementing a universal interface for the automatic exchange of data between software environments ensures consistency of information throughout the lifecycle of a project and fulfils today’s requirements to shorten time to market. As an example, with an integrated AutomationML interface in Mitsubishi’s software suite, data can be seamlessly exchanged bi-directionally with ‘ecad’ tools that also have an AutomationML interface. Mitsubishi Electric has worked with factory alliance partner Eplan to implement data exchange of hardware configurations, I/O tags and network configurations. This interface ensures interoperability all the way from first design, through engineering processes and commissioning and on through the whole lifecycle management of the automation system.
