Built for high the
Motion-Safety-Concept range will offer even higher levels of safety with the optional features, “Safely Limited Position" (SLP) and "Safely Limited Increment" (SLI). The drive-integrated safety technology is available as a plug-in module which is closely connected via the backplane bus with the device hardware of the Kollmorgen servo controller.
there is no loss of time or reaction
delay due to communication limiting factors. The seamless integration with the S700 controller also halves the whole topic of "safe return". SIL 3 can be achieved, for example, with a single resolver. The requirement for two channels could be solved by Kollmorgen internally in the drives.

The four models in the range, ±50g, ±100g, ±250g and ±500g, use the Kistler PiezoStar® shear element design which provides a wide operating frequency range and outstanding long term precision and stability. The sensor design combines PiezoStar® crystals and integral hybrid microelectronics to achieve very low sensitivity variation over the wide operating temperature range, compared with quartz and ceramic sensing element designs. The hermitically sealed, welded titanium, ground isolated, IP68 housing permits operation in harsh, dirty or wet environments and a TEDS (Transducer Electronics Data Sheet) option is available to simplify installation and set-up. Mounting by a central tapped hole on each of three sides of the cube design gives maximum mounting flexibility and allows the miniature 4- pin ceramic connector to be positioned throughout 360 Deg for convenient cable orientation.

Energy-efficient pump drive solutions P
The integrated
safety technology of the S700 servo drive is so fast that shorter distances can be selected for the sources of risks. This advantage is two-fold: Firstly, protective devices can be placed closer to the machine process - which ultimately leads to more compact structures. Secondly, higher machine speeds are possible - without having to provide the safety technology at a higher spatial distance.

ermanently full speed? Not such a good idea for pump drives! Speed control balanced to actual requirements greatly enhances the energy efficiency of pump systems. NORD DRIVESYSTEMS supplies complete pre-assembled distributed drive units for a wide performance range to 22 kW. In addition to energy savings of up to 60%, users benefit from reduced noise emissions, low wear, and increased plant service life as well as the ecological advantages. The SK 200E series comprises reliable and economical frequency inverters especially tailored to pump applications that precisely adjust power output as required. They are compatible with mains voltages worldwide. NORD configures complete
drive systems for various application areas (IP55/IP66, ATEX zone 22/3D). Integrated process and PI controller functions enable the fully automated control of process variables and compensation of disturbances – in stand-alone and mobile applications as well as in complex setups with several drives. Thanks to two analog inputs, the inverters can directly process sensor data such as pressure or flow rate. Optional signal and power plug connectors facilitate handling and ensure compatibility. A programmable energy-saving function automatically reacts to partial load operation – increasing efficiency and significantly reducing running costs.

Safety Maturity Index Tool to help manufacturers achieve Best-in-Class Safety Performance
R enter 813 enter 814
ockwell Automation today announced the Safety Maturity Index (SMI) tool, a self-guided assessment that gives manufacturers visibility into the effectiveness of their safety programs and the ability to optimise plant performance. Applicable to any industry, any plant size and any location in the world, the SMI tool helps manufacturers see where they measure in safety culture, compliance and capital. Most importantly, it provides recommendations to help achieve best-in-class safety performance. The three principal components of a successful safe workplace – culture (behavioural), compliance (procedural) and capital (technical) – are equally critical and interdependent in developing a strong, sustainable safety program. For example, creating and maintaining a robust safety
culture but not investing in safety technologies
and/or complying with standards lowers a company’s ability to provide a safe workplace. Likewise, the possibility of risk remains when manufacturers invest in safety technologies but fail to emphasise the importance of safety culture throughout the organisation.
Each safety pillar is measureable in the SMI tool using four categories – SMI 1: minimising investment, SMI 2:
attaining compliance, SMI 3: cost avoidance and SMI 4: operational excellence. By answering a series of questions, manufacturers can complete the SMI assessment and determine how they measure in each of the four categories. The report also provides recommendations for improvement, if needed. “The benefits of optimising safety through the SMI assessment can result in fewer injuries and fines, as well as improved plant productivity, greater efficiencies and enhanced employee morale,” said Mark Eitzman, safety market development manager, Rockwell Automation, who is presenting the SMI tool at the America’s Safest Companies Conference in Atlanta on Oct. 28-30, 2013. “Achieving best-in-class safety performance begins with assessing current practices companywide, and now customers can do this on their own.”

limitations. Our customers regularly require customised solutions involving bespoke products,
O configurations
and combinations. Recently, we were approached by a customer with a requirement to cool an enclosure cabinet with a maximum
operating temperature of 68°C.
Standard fan filter units struggle at temperatures above 55°C. Our customer specified that the cabinet must remain negatively pressurised;
reversing their existing system was not an option. As an
alternative solution we designed a
therefore custom
system using an Ecofit Ø 250mm fan combined with Fandis filter units. The Ecofit model has a maximum operating temperature of 70°C and was fitted so that the air was drawn out of the top cabinet. This enabled cool ambient air to be drawn in, thus providing the most thermally efficient airflow. The IP54 Fandis filters ensured that no dust or airborne debris was able to enter the cabinet. This is just one example of Axair’s flexibility and our commitment to finding the right solution. For more information on high temperature fans and fan filter units, contact the Axair team today.
