To help integrators, OEMs, and end users reduce time required to specify, design, and install multiaxis systems, Bosch Rexroth has introduced its new Cartesian Motion System (CMS): pre-configured Cartesian Robots in 1, 2, or 3 axes. The CMS offering uses standard Compact Modules and servo drives from Rexroth, and can be ordered completely pre-assembled or as a ready-to-assemble kit.
Comprising up to three axes, the CMS is designed for payloads up to 25 kg, speeds up to 1.0 m/s, and acceleration rates up to 15 m/s². Depending on the chosen axis combination and size, the motion system can execute strokes up to 1000 mm in the X axis, 700 mm in the Y axis, and 800 mm in the Z axis. The range of motion provided makes the new system ideal for pick-and-place applications in assembly cells and at transfer stations, as well as for packaging and other handling applications.
Rexroth''s CMS combines Compact Modules with mounting brackets, servomotors, controllers, cables, cable management and other necessary components to form a complete, ready-to-install handling system with a variety of communication interfaces. The system is pre-parameterized, so it is ready to "plug and play" into the customer''s application, reducing installation and debugging time. To save additional project engineering and design time, Rexroth also offers a new 3D CAD Generator. The customer simply chooses desired configuration and preferred file format, and a link to the 3-D CMS drawing is provided immediately, for download at the customer''s convenience.
Internal Rexroth Linear Motion Components ensure optimum performance: Compact Modules and their accessories have proven themselves in the field as low-maintenance, high-performance technology. The CKK Compact Modules used in the CMS consist of an extremely compact frame made of precision extruded aluminum with an aluminum cover and a polyurethane sealing strip to protect the internal components. Two integrated Ball Rail® systems, a high-precision ball screw with large screw diameters and leads, as well as double floating bearings have been tested for long service life and offer the dual benefit of high travel speeds and precision.
Servo drives with variety of field bus connections: The Compact Modules are driven by Rexroth ECODRIVE Cs servo drives with a power rating of 400 and/or 750 W. These economical drives will operate from 1- and 3-phase supply networks with an input power of up to 230 V. The maintenance-free, highly dynamic motors are available in two frame sizes. The high power density within a compact envelope -- short overall length and minimized motor mount dimensions -- is optimally matched to the Rexroth Compact Modules. IP65 protection rating allows the motors to be used in widely varying process conditions. Equipped with command communication modules like the SERCOS interface, Profibus DP, CANopen or DeviceNet, the Rexroth controllers integrate easily into different automation concepts. Thanks to their open interfaces and UL certification for the U.S. market, the drives can be used anywhere in the world.
