70 n NEW PRODUCTS March 2020 www.drivesncontrols.com Kollmorgen has announced a motion system based on its AKD2G servodrive and AKM2G servomotor which, it claims, can cut indexing, move and settle times by delivering increased torque and power in a similar or smaller package than rival systems. Because the motor and drive are matched in every way (switching frequencies, commutation algorithms and motor magnetics), they avoid the incompatibilities that can occur when using components from different manufacturers. The result, says Kollmorgen, is a system that delivers maximum performance and efficiency, even in demanding applications. The 2G motion system allows designers to decrease the size, complexity and footprint of new machines, while still getting the power and performance they need. The motors can also be dropped into existing machines to boost performance without needing to use a bigger motor. The motion system is claimed to save time and effort when evaluating vendors and component combinations. The single-cable design and the availability of dual-axis models can cut material and machine assembly costs, while improved motor and drive efficiencies reduce energy consumption. Kollmorgen www.kollmorgen.com maxon has launched a miniature (32 x 22mm) positioning controller with a similar performance to larger controllers in its Epos family, resulting in an “attractive” price-performance ratio. The Epos4 Micro 24/5 Can device is aimed at cost-sensitive single- and multi-axis applications. The functions, operation, software and accessories are derived from maxon’s existing Epos4 products. The controller is suitable for use with brushed DC or brushless EC motors up to 120W. Feedback options include Hall sensors, digital incremental and SSI absolute encoders. Dual- loop, field-oriented control, feed- forward, and observer control functions allow optimal control in a variety of applications. The digital and analogue inputs and outputs are freely configurable and matched to the functions and operating modes of maxon’s CiA-402 positioning controller. The intuitive Epos Studio start-up software, as well as libraries and programming examples for integration in a wide variety of master systems, are available free of charge. A plug-and-play evaluation board is provided for initial commissioning. The first derivative of the microcontroller is a CANopen version, which can also be addressed using RS-232 or USB. An EtherCat version will follow soon. maxon motor 01189 733337 www.maxongroup.com/maxon /view/content/epos-detailsite Rockwell Automation has announced a new generation of electronic overload relays to protect motors and avoid downtime. The Allen-Bradley E100 relays are claimed to measure motor load current loads and to model motor temperatures more accurately, shutting down the motor if there is a risk of damage due to overheating. The relay comes in basic and advanced versions. The basic model has two user-adjustable trip-class settings of 10 and 20. The advanced model has four settings (10, 15, 20 and 30). Above 100A, the advanced model can use external current transformers to achieve a maximum rating of 800A. The relays can mount directly onto 100-C IEC contactors up to 100A, as well as Bulletin 500 Nema contactors. Options are available to detect jams and earth faults, and to reset the overload remotely. Rockwell has also developed motor protection circuit- breakers that mount on its Allen- Bradley 100-C or 100-K contactors to create two- component motor starters. The Allen-Bradley 140MP breakers provide magnetic short-circuit protection and thermal-overload protection up to 32A, and interrupting capabilities up to 100kA at 400V. The devices comply with IEC 60947-4-1 for motor protective switching, and IEC 60947-2 for circuit breakers. They are also UL-approved for use in group installations, eliminating the need for individual branch short- circuit protective devices for each motor circuit, thus cutting panel space, installation and wiring times, and costs. Rockwell Automation www.rockwellautomation.co.uk Miniature positioning controller has ‘attractive’ price-performance ratio Electronic overload relays measure and model motors more accurately Matched motion system delivers enhanced performance in a compact form factor Schneider Electric has enhanced its TeSys island digital load management system in several ways, including two new configurable application avatars – for pumping and conveyor applications. These are easily to integrate, and users can choose between remote (PLC driven), autonomous (variable driven) or local (operator driven) control modes. The autonomous mode supports flexible load management. The TeSys island system can now generate alarms and alert of impending failures. It now supports Profibus and Profinet, and can operate as a native device within Siemens’TIA Portal environment. www.se.com Nord Drivesystems has optimised the design of its IE3 asynchronous motors, improving their assembly and operation, without changing their electrical data or dimensions. The motors’ cooling fin shapes have been optimised for better heat dissipation and assembly, and allow unhindered airflow around revised terminal boxes which avoid sharp edges. The incremental encoder mounting has been improved. The shock- resistant encoder is outside the airflow, improving the cooling effect further. www.nord.com Sick has released safety-certified versions of its TTK70 and TTK50 magnetic absolute linear encoders with Hiperface interfaces. The encoders are certified to SIL2 (IEC 61508) and PLd (EN ISO 13849) for safety- related motion supporting SLS (safely-limited speed) safety functions in safe drive controls. The TTK70S has a 70mm-long housing and a measurement length up to 4m, while the TTK50S has a 50mm housing and a smaller read head, for measurements up to 1m. www.sick.co.uk
