Motek 2016

A few fair impressions

The 35th Motek took place from October 9 to 12, 2016 in Stuttgart (Germany). CAN was again part of the international trade fair for automation in production and assembly.

The Motek fair is an event in the fields of production and assembly automation, feed technology and material flow, streamlining through handling technology, and industrial handling. It focuses on aspects of mechanical engineering and automation and on the presentation of entire process chains. Motek 2016 presented robot systems integration in a format with visualized, hands-on robotics process capability in a range of applications: complementary, congenial, collaborative, cooperative. Most of the shown robots use a CAN interface for communication. Every year, over 900 exhibitors meet in the Stuttgart exhibition center with an international public of around 35 000 specialist visitors, who travel from nearly 100 countries around the world.

Taking a look at the different products at the exhibition, CAN caught the eye here and there. Dunkermotoren (Germany) showed its BG 95 dPro CANopen drive again, which is based on a brushless DC motor with an output of over 1 kW. Ott (also Germany) exhibited its electronic motor with integrated control electronics. It comes with a CAN network with several motors connected to one another. A 4Q servo controller is part of the electronics. The CAN channel of the controller can parameterize various functions such as ramps, speed, torque limiting, timers, automatic drive profile operation, and more.

Another product at the fair was the valve system solution ES05 for elementary pneumatics by Aventics. The valve can be controlled via CANopen. Sick (Germany) was also part of the exhibition and showed a range of its CANopen-based encoders and inclinometers. Smart Testsolutions (Germany) released a new generation of its test software, which now support three CAN interfaces and Ethercat communication capabilities. In addition, the software has been enhanced to better address cell voltage monitoring (CVM). Another release of the company was the MCM-Intelli Probe cell monitoring system for fuel cell, battery, and electrolysis applications. The system addresses both laboratory and mobile use cases and is characterized by withstanding a voltage of 1,4 kV. “The isolation resistance is of high importance when multiple channels are to be measured at high voltages”, says Wolfgang Neu, Founder and CEO of Smart Testsolutions.

Despite their isolation resistance, the measurement modules are small: One module that can handle up to ten channels (and ten corresponding cells) measures 100 mm x 30 mm x 10,5 mm. It can be applied in stationary lab environments as well as in mobile applications such as vehicles or ships alike. If more than ten cells have to be monitored, multiple modules can be combined like Lego bricks. No wiring is required. Another feature is the capability to select different measurement ranges; test engineers can chose between a range from -1 V to +5 V or -3 V to +3 V.

A complete measurement system integrates up to 42 ten-channel voltage monitoring modules, enabling users to concurrently acquire the voltages of 420 channels, a link module to connect to supply, and communications lines. The last measurement module includes the bus termination resistances. Data transfer is achieved through a CAN network. Also new is the enlargement of the system with the MCM Master Module, which makes data binding to the PC via CAN and other bus interfaces available and allows local data pre-processing. Thus the Master Module extends the functional extent of the measuring system.
