The need for extremely fast response, using non-standard motors, has led Spanish company Rius Textile Machinery of Barcelona to standardise on Unidrive SP AC drives from Control Techniques for its direct and sectional warping systems and knitting machines.
位于西班牙巴塞罗那的Rius Textile Machinery公司需要相应迅速的非标电机，他们选择艾默生CT的Unidrive SP交流驱动器作为标准驱动系统，并将其应用在他们的直接和分条整经机系统和编织机中。
In the face of aggressive competition, the company is carving out new market niches - medical / sanitary, agro-textiles, mechanical and food wrappings - and producing machines designed for leading edge fibres for high performance products.
面对日趋激烈市场竞争，该公司正在积极开辟新的细分市场——医疗/保健、农纺织品、机械和食品包装——并研发那些生产流行布料的高性能纺织机器。
"Our machinery has to accelerate very fast and maintain precise torque control, to prevent fibres breaking," explains Valenti Ruis Jr, Rius Textile Machinery's sales director. "We often use non-standard motors such as OML high-speed, low inertia motors, which have extremely dynamic performance. Other motors have completely different characteristics, but we find that the Unidrive SP from Control Techniques can be set up to give optimum performance across the range. And, because we export some 90% of our output worldwide to around 96 countries, it's important that our customers are assured of local support from Control Techniques' network of drive centres.
“我们的机器必须加速快、力矩控制精确，纺织物才不会断裂”Rius Textile Machinery公司销售经理Valenti Ruis Jr解释说。“我们经常使用非标电机（例如OML高速、小惯性电机），这些电机动态性能极高，其他电机特性则没有这种性能。我们发现艾默生CT的Unidrive SP经过设置后，可为所有产品提供最优性能。"另外，我们90%的产品出口至全球约96个国家，艾默生CT的驱动中心网络可为我们的客户提供本地支持，这一点非常重要。”
The Rius' high performance sectional warp winding machine gathers together up to 2,000 yarns and prepares the yarn for weaving by winding it in a prescribed sequence onto a beam (drum). The machine is designed to warp all types of natural and synthetic yarns on beams up to 1,000mm diameter.
Rius的高性能分条整经卷纱机将2000股纱线拢到一起，并按照预定顺序将其缠绕到经轴（经鼓）上，等待纺织。机器可以将各种类型的天然和合成纱线整经到直径1000毫米以下的经轴上。
Lateral displacement of the warping carrier is completely controlled by the computer, with automatic positioning for each section. The warper is driven by a15 kW OML fast response, low inertia motor at constant speeds of up to 1,000 metres/minute. "The speed must be absolutely constant and stable during winding," explains Valenti Rius Jr, "and at a constant tension. As the diameter of the wound drum increases, its speed is decreased to keep the winding speed constant."
整经托架的横向位移完全由电脑控制，并且每一条均可自动定位。整经器由一个以1000米/分的恒定速度运行的15 kW OML电机驱动，该电机响应快、惯性小。“在卷纱的时候速度必须绝对恒定和稳定，”Valenti Rius Jr 说，“同时张力也要保持恒定。当经鼓直径增加时，为了保持卷纱速度恒定，其旋转速度必须降低。”
This is achieved with the use of Control Techniques' winder software loaded onto the plug-in SM-Application module fitted into the Unidrive SP. In addition, an SM- Encoder Plus is fitted to provide an interface for an additional encoder to be connected to the Unidrive SP, to be used as position and speed feedback for the drive.
使用艾默生CT的络纱软件即可实现这一功能，该络纱软件加载插入式SM-Application模块上，该应用模块插入Unidrive SP中。此外，Unidrive SP上还安装了一个SM- Encoder Plus 编码器模块，可为额外的编码器提供接口。额外的编码器连接在Unidrive SP上，用于向驱动器反馈位置和速度信息。
The machine has two touch-screens, for the warping carrier and beaming head-stock, with overall control from a PLC that sends the warping speed to the drive. The drive speed is calculated in the drive, taking account of yarn thickness.
机器有两个触摸屏，分别用于整经托架和经轴头架，由PLC提供整体控制。整经速度由PLC向驱动器传送。驱动速度在驱动器内计算，计算时须考虑纱线厚度。
Other machines made by Rius Textile Machinery also use Commander SK AC drives, for small power applications, as well as Unidrive SP drives.
Rius Textile Machinery生产的其他小功率应用机器也使用Commander SK交流驱动器，当然也使用Unidrive SP驱动器。
The Unidrive SP AC variable speed drive range spans 0.37kW right up to 1.9MW. Unidrive SP is the world's most advanced 'solutions platform' AC drive, configurable into five operating modes - open and closed loop, vector, servo and regenerating modes - connectivity to most industry standard networks, configurable for all types of AC motors, including linear motors, and accepting 14 position feedback protocols. With a range of plug-in module options, its on-board PLC can be supplemented, as in this case, with programmable modules.
Unidrive SP交流变速驱动器功率介于0.37kW到1.9MW之间，是全球最先进“方案平台”交流驱动器，可配置为5种运行模式——开环、闭环、矢量、伺服和再生模式——可连接至绝大多数通信网络，可针对所有类型的交流电机（包括直线电机）进行配置，且可接受14种位置反馈协议。该驱动器有大量的模块选件可选，也可选择内置PLC的应用模块。
