Diversified industrial manufacturer Eaton Corporation will be presenting the new PowerXL variable frequency drives for a rating range of up to 250 kW at this year's SPS/IPC/Drives fair in Nuremberg. The company is thus logically expanding its strategy of applying the Lean methodology to the engineering in machine and panel building. Pluggable modules enable the PowerXL variable frequency drives to be incorporated quickly and simply into Eaton's SmartWire-DT connection and communication technology which completely eliminates the need for conventional control circuit wiring. The new PowerXL variable frequency drives thus give users from the machine building sector as well as from the materials handling and building services sectors an easy-to-install, operator-friendly and energy efficient solution for driving devices such as pumps, fans, conveyor belts, cranes, winding machines, compressors or lifts.

The new PowerXL variable frequency drive series currently consists of two models: The DC1 Compact and the DA1 Advanced Machinery Drive. The DC1 is the basic model covering ratings from 0.37 to 11 kW, and was developed for applications where robust design, availability and universal functionality are the main requirements. The DA1 series is designed for ratings from 0.75 kW to 250 kW, and is suitable for the most demanding solutions requiring high performance. The PowerXL variable frequency drives also offer different open and closed-loop control methods. The DC1 controls the motor with U/f characteristics and also enables an increased torque. The PowerXL frequency inverters are thus able to operate the motors at 150% of the rated power for 60 s and at 175% for 2 s. The DA1 models also offer the user the possibility of sensorless vector control (SLV) as well closed-loop control with a rotary encoder (CLV). In sensorless vector mode the DA1 can even move from rest with a 200% torque and without the use of an encoder. The DA1 series is provided with PLC functionality and offers, in addition to a standard integrated PID controller, the possibility of powerful solutions for different applications such as cranes, lifts, winding machines and compressors.

User-friendliness was a prime objective in the development. Self-explanatory type codes, autotune functionality and convenient parameterization (with only 14 standard parameters) simplify configuration and commissioning. As well as programming via the keys on the device or alternatively via a PC, the user can copy the parameter settings from one device to another quickly and simply using a Bluetooth PC stick with an RJ45 interface.

The PowerXL variable frequency drives come as standard with the Modbus RTU and CANopen fieldbus system. The user can connect other fieldbus systems such as Profibus, Profinet, DeviceNet, EthernetIP, EtherCat, Modbus TCP and BACnet easily via fieldbus modules. As an alternative to the fieldbus connection, the PowerXL variable frequency drives can also be incorporated in the SmartWire-DT communication system. This makes it possible to not only parameterize the PowerXL frequency inverters centrally via the SmartWire-DT interface, but also to send them control commands and read diagnostic data from them. The device can also be controlled via a PROFIdrive profile which makes the full function spectrum of the PowerXL frequency inverters available.

With the focus on energy efficiency, the DA1 series supports both the standard three-phase motors that normally comply with the current IE2 and IE3 standard, as well as the highly efficient permanent magnet motors that are designed for the future IE4 standard. The devices also feature an energy optimizer that can automatically reduce the motor voltage with light loads.

The PowerXL frequency inverters supply full power up to ambient temperatures of 50°C (IP20). Eaton also offers the DA1 models up to 160 kW with protection to IP55. All devices come with international approvals (CE, cUL, UL, C-Tick, Gost-R, RoHS, DNV) and with single-phase and three-phase voltage inputs of 115 V, 230 V and 400/480 V are ideally suited for global use.

Enables Control and Notification in Remote Parts of Plants Where Wiring is Too Costly or Not Possible

Honeywell announces the release of the new Limitless™ Wireless Operator Interface, WOI Series, which expands Honeywell’s Limitless™ wireless switch and receiver portfolio by providing a packaged pushbutton controller for manufacturers and OEMs. The WOI Series adds a human interface device to the product-driven interfaces of the Limitless™ portfolio. With both momentary and maintained contact options, the Limitless™ Series now offers wireless control from both person and position.

Honeywell’s Wireless Operator Interface is a controller designed to wirelessly turn on and off equipment (pumps, motors, drives, conveyors, and other industrial equipment), open or close gates/doors, or provide notification to remote locations. The WOI Series can be used in rugged industrial environments to notify appropriate departments when there are quality, machine, material out-of-stock, or other manufacturing issues.

“The WOI Series provides a control option for users looking to avoid the wiring costs, maintenance issues, hazards, time and engineering that comes with a ‘wired’ push button,” said Joseph Citrano, senior global product marketing manager, Sensing and Control. “This new device expands Honeywell’s Limitless™ wireless portfolio that includes monitors, din-rail receivers, global limit switches, and heavy-duty limit switches.”

Designed for flexibility, the user can choose and install a desired operator (22 mm rotary switch, key switch, key) or utilize one of Honeywell’s pushbuttons. It communicates through Limitless™ receivers that provide PLC inputs or relay outputs connected directly to equipment to turn on LEDs or start/stop industrial equipment.

The Limitless™ wireless network is an easy and cost-effective solution for those looking for a reliable wireless solution. It includes the WDRR Din-rail receiver, WPMM monitor, WLS heavy-duty limit switch, and WGLA global limit switch. The entire Limitless™ solution utilizes the global, license-free RF wireless 802.15.4 WPAN protocol that provides up to a 305 m [1000 ft] line-of-sight communication range, and prolongs battery life with advanced power management technology.

The Limitless™ WOI Series potentially could be used in industrial applications such as CNC action, conveyors, door and gate action, lifts, material handling, motor drives, presses, pumps, quality control buttons, specialty machines, stop/start machinery, stop/start production, and valve action. Potential transportation applications include agricultural equipment and movable machinery.

With increasing health and safety demands and the need to protect valuable equipment, Finder’s new 70 Series modular rail-mounted monitoring relays provide a solution by offering maximum flexibility in monitoring a range of electrical supply parameters, in compact, easy to adjust units. For example, machine safety legislation (IEC/EN/BS60204-1) requires that portable or semi-portable motor-driven equipment be prevented from starting up in the wrong direction should the local phases be reversed, and a phase reversal monitoring relay can provide for that.

Finder’s new relays are ideal for monitoring supplies to machinery, equipment, and installations where failure or variation outside acceptable limits may result in damage to equipment, danger to personnel, or disruption to critical processes or procedures. Featuring ‘positive safety logic,’ the 70 Series will ensure that any failure mode results in the output relay assuming its de-energized position. With a selectable fault memory (lock-out), safety is increased by preventing uncontrolled restarting of equipment.

With a wide range of adjustments to maximize application flexibility, the monitoring relays feature two or three colour LED indicators for immediate visual indication of supply status. The functions and values are programmable from the front face, simplifying set-up and adjustment.

Within the 70 Series range are units designed to monitor single and 3-phase supplies for under-voltage, over-voltage, voltage within set limits, and for neutral loss, phase loss, phase rotation and asymmetry. The four monitoring relays in the 70 Series range (three of which are multifunctional) offer a selection of voltage limits between 170 – 270 for single phase, and 300– 480 for three-phase supplies, a switch off delay time between 0.5 – 60 seconds, and 4 – 25% variation of phase asymmetry. The modules are available in 17.mm or 35mm, dependent on type.

The revolutionary SmartWire-DT system from Eaton’s Electrical Sector, which virtually eliminates the need for conventional control wiring in panels and on machines, is now even more versatile and convenient. This follows the addition of devices with integral SmartWire-DT connectivity to two key product ranges – easy800 control relays and PKE motor-protection circuit breakers.

In many applications, easy800 programmable control relays with SmartWire-DT make it possible to implement sophisticated control systems without the need to use programmable controllers (PLCs), which means big savings in costs and complexity. In addition, Eaton’s easySoft-Pro software makes easy800 relays simple to program, even for users who have no specialist programming knowledge or experience.

The new easy800 relays are suitable for applications with up to 320 I/O and are programmed using straightforward and well-known ladder diagram techniques. The easySoft-Pro programming software now includes SmartWire Assist to configure external devices, allowing control systems that incorporate the new relays to be drawn, configured, programmed and tested using just this one intuitive software package.

Equally well suited for use in control systems based on easy800 relays, and those based on conventional PLCs, PKE motor-protection circuit breakers with SmartWire-DT allow users to monitor the operation of their motors in detail and in real time. The PKE units can report via the SmartWire-DT connection a wide range of operating parameters that include motor current, motor fault conditions and overload status. This is achieved without the need for additional hardware like current transformers and specialist relays, which are not only costly to buy, but are also inconvenient to fit and wire.

A key benefit of the information supplied by PKE units with SmartWire-DT connectivity is that, in many cases, it allows developing problems to be identified and addressed before a motor trip occurs, thereby greatly reducing downtime and costly production losses.

SmartWire-DT from Eaton is a powerful and versatile communications system that enables switching and control devices, such as contactors, circuit breakers and pushbuttons, as well as analogue I/O devices, to be connected quickly and simply using pre-fabricated plug-in cables. This saves time in building and testing control systems, as well as virtually eliminating the risk of wiring errors while greatly increasing the ease with which future modifications can be made.
