Motion Control Motion Controller for Precision Linear Positioners and Rotation Stages PI (Physik Instrumente) LP is offering a motion controller for closed-loop precision positioning systems. The C-884, four-axis digital servo controller was designed to control motorized linear translation stages and rotary positioners with very high accuracy and repeatability. The high-speed encoder interface allows the use of the latest direct-metrology linear and angular scales with resolutions down to the nanometer and microrad realm and below. PI’s controller is equipped with a dual-core architecture for fast servo handling and command interpretation. A wealth of software tools are provided for ease of operation. The included PIMikroMove software helps the user to get up to speed quickly, without the need for writing a single line of code. For programmers PI’s General Command Set (GCS) simplifies the development of custom applications, reducing the risk for errors, because the commands for all supported PI devices are identical in syntax and function. Through the use of the GCS command set with its convenient functions, the orientation phase and application development process is vastly accelerated. The GCS commands are available at the controller terminal, in macros and in the form of a universal driver set for LabVIEW (VIs), Windows dynamic link libraries (DLL) and Linux libraries Other useful functions for programmers and users as well are the data recorder (real-time recording or motor voltage, velocity, actual position and position errors, etc.) and the stand-alone capability, which is made possible by means of a computer-independent macro programming language that runs on the controller. This servo positioning controller supports several motion profiles, linear vector motion, point-to-point motion. PID parameters can be changed on the fly, the servo update rate is 20 kHz. Communication is through industry standard TCP/IP, USB and RS-232 interfaces. Scalable AKD Servo Drive-Based Solutions Satisfy Simple Single Axis Control With the recent additions of the AKD PDMM and AKD BASIC to its servo drive family, Kollmorgen now has available a complete suite of scalable motion solutions that enable OEMs to simplify the design, reduce the size and improve the performance of virtually any machine. Scalable solutions enable machine designers to leverage a single drive platform to satisfy unique motion needs, from simple single axis control up to 128 www.e-DriveOnline.com axes of fully programmable and tightly synchronized motion, across machine designs. “Each product in the AKD platform fits a specific need in the machine market, so a machine designer is sure to find a motion solution that seems tailor-made for the machine architecture. The result is an optimized solution at COTS pricing with all the performance that the market has come to expect from Kollmorgen,” said Kevin Liu, product manager of Industrial Automation. “The flexibility of the AKD platform is also ideal for machine builders who are looking for a migration path from a traditional controller to a modern digital motion bus based system. The AKD platform supports both solutions and leverages the same configuration software to make the transition even easier.” AKD Ethernet-based servo drives enable machine builders to standardize on a single drive family with a common Graphical User Interface (GUI) across the power range (up to 24 Arms continuous and 48 Arms peak). This results in optimized machine performance, throughput and accuracy across multiple applications, while minimizing engineering time and costs associated with stocking, understanding and programming multiple types of drives. These drives offer pug-and-play commissioning for instant and seamless access to everything in a machine. AKD servo drives are available in a wide range of connectivity and control options including EtherCAT, EtherNet/IP, CANopen, Profinet as well as Analog and pulse train command control options. AKD PDMM combines a high-performance multi-axis motion controller, complete IEC61131-3 soft PLC, EtherCAT master, and AKD servo drive in a single, compact package. This enables OEMs to lower machine costs, reduce panel space by 50 percent or more and simplify wiring and integration, while increasing system flexibility, scalability and motion performance. AKD PDMM is well suited for applications where precise synchronization of multiple axes of motion is vital, and can reduce the time required to commission complex systems from weeks or more to days or even hours. AKD BASIC incorporates a programmable single-axis motion controller into the existing AKD drive footprint, enabling OEMs to build a more compact and cost-effective machine by eliminating the need for a separate PLC. The registration correction, camming, s-curve and free-form motion profile capabilities delivered by the integrated motion controller, combined with the simplicity of BASIC programming language and a built-in Program Editor with debugging tools, enables machine builders to reduce development time by up to 70 percent and to execute complex processes, faster than is possible with conventional servo drive-based options.
