The German precision drives specialist Wittenstein has developed what it claims is the first fully scalable servo-actuator platform. The flexible platform, called premo, made its debut at the recent SPS IPC Drives show in Germany. Wittenstein says that it “sets new benchmarks in terms of size and power density”.
The Japanese precision motor manufacturer Nippon Pulse has collaborated with the German encoder-maker Siko to produce what they claim is the first linear motor to incorporate a non-analogue magnetic linear encoder. The scale-less SL083 motor is aimed at positioning applications that need the repeatability, reliability and robustness of a linear motor, with a resolution and repeat accuracy of up to 5µm.
Cognex has announced a family of compact, standalone vision systems that deliver data at PC-like speeds, without needing a PC. The In-Sight Micro 8000 cameras include the “world’s smallest” self-contained 5-Megapixel vision system.
At the recent SPS IPC Drives show in Germany, Yaskawa, and its German controls subsidiary Vipa, unveiled a system that implements motion control functions directly in PLCs.
ABB has entered the competitive market for Scara (selective compliance articulated robot arm) robots for the first time with a family of three modular robots capable of handling loads up to 6kg and achieving reaches from 450–650mm.
At the recent SPS IPC Drives exhibition in Germany, Yaskawa unveiled the first model in a new generation of frequency inverters, claiming that it is among the smallest on the market, as well as being easy to set up and operate. The GA77 drives, available in ratings up to 630kW, can be used to control asynchronous, permanent magnet, or synchronous reluctance motors, without needing auto-tuning.
Danfoss has added an optional software function to its VLT AutomationDrive FC 302 that, it says, will deliver the precise positioning and synchronisation of a servodrive – without the cost and complexity. An FC 202 equipped with the new Integrated Motion Controller (IMC) function can be used to control asynchronous or permanent magnet motors, with or without encoders.
Sumitomo (SHI) Cyclo Drive has collaborated with the Swedish motor manufacturer HDD Servo Motors to develop a compact, precision, hollow-shaft motor-gearbox that, they claim, is half the length of conventional rotary drives with comparable performance.
The Swedish industrial communications specilaist HMS Industrial Networks has developed a PC interface card that supports numerous industrial Ethernet standards, allowing users to connect PC-based slave applications to EtherCat, EtherNet/IP, Modbus TCP, Profinet IRT/RT, Powerlink and standard TCP/IP.
The Brazilian motors and controls manufacturer WEG has launched a Class-10 motor protection circuit breaker which, it claims, is the smallest on the market. The MPW80 breaker is aimed at applications requiring high short-circuit switching capacities and compact dimensions.
National Instruments (NI) has announced a family of industrial controllers designed to address the requirements of advanced Internet of Things (IoT) applications. The company says that the controllers will simplify systems, cut costs, and shrink footprints by integrating control functions, processing and various types of I/O – including vision and motion – into a single high-performance controller.
Emerson has added two new models to its Control Techniques family of variable-speed drives, which have been designed specifically to operate at high speeds. The Unidrive HS30 and HS70 VSDs are capable of output frequencies of up to 3kHz, and are thus controlled products under new laws in the EU and US that cover the export of “dual-use” technologies that are normally used for civilian purposes but may have military applications, or could be used in equipment such as high-speed centrifuges used to produce weapons of mass destruction.
ABB has announced a multi-purpose industrial robot capable of lifting the company’s heaviest-ever payload, adding that it is also 25% faster than its rivals and has a lower total cost of ownership. The IRB 8700 robot can handle payloads of up to 800kg (or 1,000kg with its wrist down) and has a reach of 3.5m. There is a second version available with a reach of 4.2m and a maximum payload capacity of 550kg (or 620kg with the wrist down). Both versions have an unusually high moment of inertia of 725kgm2.
Schneider Electric announced a new generation of variable-speed drives aimed at machine-builders, at the SPS IPC Drives exhibition in Germany. The bookshelf-format Altivar 320 and the compact–format Altivar 340 support open-loop control with torque-sensitive operation, even at low speeds, as well as closed-loop control for applications requiring velocity-sensitive operation or precise positioning.
ABB has unveiled two new drives at the SPS IPC Drives show in Germany which, it says, will allow machine-builders to improve the performance of their machines, while cutting the costs of integration and maintenance.
