MOOG TO PREVIEW NEW MACHINE-CONTROL CONCEPTS
27 March 2000 - Moog Controls
| Moog’s new machine-control technologies, which will be exhibited through live demonstrations and static displays at NPE Booth No. #1468, are designed to provide precise machine control, reduce system costs and save energy. Distributed intelligence at the component level is an integral part of Moog’s control concepts. |
Moog Inc., Industrial Controls Division, to preview concepts representing the next generation in machine-control technology for injection-molding machines, blow-molding machines and material-handling robots. Moog’s new machine-control technologies, which will be exhibited through live demonstrations and static displays at NPE Booth No. #1468, are designed to provide precise machine control, reduce system costs and save energy. Distributed intelligence at the component level is an integral part of Moog’s control concepts. "Moog’s new products and technologies address overall industry trends toward improved performance, reduced energy consumption and reduced control systems costs," said Sean Insalaco, marketing manager, Moog. "NPE is the perfect forum to demonstrate how these control solutions can be leveraged in the plastics market." The Next Generation
Using an Injection Molding Technology Demonstrator designed exclusively for NPE, Moog will compare three unique control solutions for the closed-loop injection process: 1) servo-pump solution; 2) variable-speed pump solution; and 3) intelligent manifold with servo-proportional valve solution. Plots of real-time data throughout an injection cycle will be displayed, and position and pressure signals from all three solutions will be overlaid to compare and contrast the three technologies. In demonstrating these three control solutions, Moog will show: How fixed-speed, variable-displacement servo-pump technology provides cylinder position and pressure control directly from the pump, offering a more cost-effective solution by lowering installation costs and reducing energy consumption;
How variable-speed, fixed-displacement pump technology (an alternative to servo-pump technology), using a gear pump, Moog’s brushless motors and the company’s T200 Programmable Servo Drive, offers high performance velocity and pressure control, while reducing energy consumption and noise levels;
How the intelligent manifold, an injection manifold with an embedded motion controller, creates specific axis functions, demonstrated by closed-loop velocity and pressure injection axis control. The technology eliminates the need for OEMs to assemble and test hydraulic solutions on the machine at the component level.
Other next-generation technologies being showcased by Moog include a Motion Control Valve, which features a device network interface and built-in single-axis controller for reduced system costs and improved diagnostics and performance. The display is designed to demonstrate Moog’s ability to provide distributed machine-control solutions, moving the loop closure to the device level. Moog’s Mirai injection-molding machine controller also will be on display. The Mirai integrates Moog’s latest injection-molding machine controller with new software algorithms that constantly monitor and adjust for molding conditions, enhancing the quality of the molded part. Fuzzy V/P logic automatically sets and adjusts the switching of the V/P point. Adaptive control offers automatic adjustment of control gains and optimization of control during each molding cycle. New Products
In addition to previewing its next generation of control technologies, Moog will display some of its newest products, including: D680 Series Servo-Proportional Valve: Moog’s high performance, D680 Series direct-drive piloted servo-proportional valves feature a two-stage construction with a Mini-DDV pilot stage. Because of the Mini-DDV, the valve dynamic performance is nearly independent of system pressure. The D680 Series, the highest dynamic valves on the market, are available in sizes D05-D08, with flow ranges of 8 gpm to145 gpm at 150 psi. L180 Compact Digital Servo Drive: Moog’s L180 Compact Digital Servo Drive offers high-performance servo control with simplified installation and wiring. Its fully digital PID control loops and advanced signal processing algorithms provide high motor dynamics and smooth low-speed response to increase system throughput. The compact package with integral power supplies, servo amplifier, limit-switch inputs and high-power regen resistor reduces wiring costs and frees up cabinet real estate. G330 Series Brushless Servo Motors: Moog’s mid-range G330 Series Brushless Servo Motors deliver high-dynamic servo performance for higher-duty cycle applications. The G330 Series come in three frame sizes with two stack lengths per motor.
