CANopen Drives, Single/Dual-Axis

CNC vendor NUM has added a family of single- and dual-axis CANopen drives to its range. The new drives provide economic solutions for positioning requirements on machine tools, extending NUM's high performance CNC control range in a way that helps customers to build machinery with highly optimised and cost-effective units of hardware. The new intelligent CANopen drives are available in seven single-axis versions with output ratings from 8.9 to 100 Arms continuous (10 to 141 A peak), and three dual-axis versions with output ratings from 6.3 + 6.3 to 20 + 20 Arms continuous (10 to 35 A peak). These options provide machine tool builders with a 'granular' choice to ensure that the control system hardware's capabilities match the machine specification. The drives are an extension of NUM's long-established drive range ? NUMDrive C with its book-style form-factor. These drives offer one of the highest power densities on the CNC market, together with a simple assembly concept for building large multi-axis systems. Both of NUM's CNC controller kernels, Flexium and Axium Power, are available with CANopen interfaces and are compatible with the new drives. The CANopen drives implement a subset of the standard DSP 402 drive profile and are ideal for performing auxiliary tasks to the coordinated multi-axis control of the machine's tooling, such as feeding and unloading material. Built-in intelligence means that the drives are extremely simple to program and use, and can perform sophisticated movement profiles following a single command. Development is further simplified by NUM's development software, which automatically recognises the drives and provides all the required libraries and functions blocks.
