Editor’s Choice ABB Introduces Foundation for an All-Compatible Drive Portfolio ABB’s AC drive portfolio has introduced a new era in control panel design, featuring an intuitive, high contrast and high-resolution control display, enabling easy navigation. Many flexible data visualizations including bar charts, histograms and trend graphs, help users to analyze processes, with assistants available to simplify set up. The menus and messages are customizable for specific terminology for applications. An integrated USB port also allows connection to the PC tool. The ACS880 series will be available as single drives, multi-drives and drive modules, with a wide power range and voltage range up to 690 V. At the heart of the ACS880 series is direct torque control (DTC), ABB’s motor control technology. These industrial drives are flexible and can be customized to precise needs of any range of industries including pulp and paper, metals, marine, material handling, mining, cement, power, chemical, oil and gas. The drives support the same software used for ABB’s AC500 PLC, CoDeSys programming environment, in accordance with IEC 61131-3. This commonality allows easy integration of the drive and PLC. The ACS880 drive modules are designed for machine builders or system integrators to integrate into their own solutions. The drive modules include everything that is required for a complete single or multidrive configuration. In addition, a wide selection of electrical and mechanical kit accessories and detailed design documentation is available. The drive modules will initially be available with inverter power up to 300 hp and diode-supply unit (DSU) up to 850 kVA, 380 to 500 V, with plans to extend to higher powers and wider voltage range. Installing an Energy-Efficient Motor Helps Reduce Losses While Increasing Profits By upgrading to a higher, more energy-efficient motor, facility managers can improve their equipment reliability, increase productivity and reduce downtime and repair costs. The Copper Development Association (CDA) recommends that individuals involved in the specification, design, selection and installation of electrical motor systems adopt a motor management program, which examines a facility’s needs whether to replace an old worn-out motor or specify a new unit. Working with government and industry-based motor experts, CDA has created a comprehensive three-part Motor Management Program. Part 1 involves creating a motor inventory and developing repair and replacement guidelines. One of the least cared-for and maintained industrial tools in 4 Summer 2013 the workplace today is the electric motor. When not properly administered, motors can cost businesses billions of dollars in wasted energy and operating costs annually. CDA, in conjunction with the Washington State University (WSU) Energy Extension Office, offers hands-on training and assistance to companies, military and utilities to develop motor management plans. Once a plant’s motor inventory is collected, a company can use a free data management software application, such as MotorMaster+, which is available for free by the Department of Energy, to compare the cost of repairing the motor versus the cost of replacing it with a new unit. The data can then be referenced for future needs including identifying where motors can be sourced locally if replacement is required; scrapped or repaired and stored in inventory; or whether regular periodic maintenance is vital for reliability and efficiency. Improve Productivity, Simplify Maintenance And Protect Workers with Safety EncoderBased Safe Motion Solution Pepperl+Fuchs has introduced RVS58S Safety Encoders and VBA-2E-KE4-ENC-S AS-Interface Encoder Input Modules. This safe motion solution improves machine productivity and enhances worker safety by detecting zero-speed, over-speed and motion direction to ensure safe machine access during setup and maintenance. The system integrates into new machines or existing equipment, and is well suited in applications that demand SIL3, PL e and Category 4 certification. RVS58S incremental encoders have a sin/cos interface, 1,024 or 2,048 signal periods and are thermally stabilized for high resolution interpolation. They operate at 5 VDC ±5 percent and deliver a maximum output frequency of 200 kHz in operating temperatures ranging from -20°C to 80°C. They are rated to handle axial shaft loads of 40 N at maximum 6,000 RPM or 10 N at maximum 12,000 RPM, and radial shaft loads of 60 N at maximum 6,000 RPM or 20 N at maximum 12,000 RPM. VBA-2E-KE4-ENC-S ASInterface safety modules feature a 22.5 mm wide housing to minimize cabinet space requirements, and snap into place on a standard 35 mm mounting rail. Each module provides two safe inputs for incremental encoders that monitor the standstill, rotational speed and direction of rotation on up to two axes of motion, and sends a safe signal via the AS-Interface network when a value falls below a set threshold. www.e-DriveOnline.com http://www.e-DriveOnline.com
