Eaton PowerXL DE1 Variable Speed Starter

Eaton Logo

A New Species

The new Variable speed starter (VSS) from Eaton offers alternatives for drive engineering

The increasing automation of machines and the increasing legal requirements with regard to energy efficiency have resulted in a significant rise in the demand for variable frequency drives. At the same time the motor starter has established a strong position on the market. In order to bridge the gap between the two, Eaton is now offering a new device class: the Variable speed starter (VSS).

Electrical speed control using variable frequency drives continues to gain importance. The Motor Regulation EC 640/2009 of the European Union is a driving force here, stipulating the mandatory use of IE3 motors directly on the grid or likewise the use of IE2 motors with variable speed drives from 2015. This means that there is an increasing move away from the motor starter towards the variable frequency drive, particularly with simple applications.

Benefits of the motor starter and variable frequency drive combined

There is clearly a gap between these two most widely used methods of controlling electric motors. One the one hand, there is the motor starter with its easy handling and high level of reliability and yet limited functionality. On the other hand, the variable frequency drive provides the required variable motor speed and a wide range of functions, but involves a greater degree of complexity. The move towards the variable frequency drive therefore presents many users with some challenges since it is a highly complex device and normally requires a comprehensive knowledge of drive engineering.

As a pioneer and one of the leading specialists for all aspects of switching, protecting and driving motors, Eaton has developed a new device class that combines the benefits of the motor starter with those of the variable frequency drive. The so-called Variable speed starter (VSS) can be handled as easily as a motor starter but offers the possibility of variable speed control at the same time.

DE1 large

 

Simplicity at first glance…

Eaton is launching the new device class under the product name PowerXL-DE1, first of all in two sizes. The slim-line FS1 version with a width of only 45 mm is ideal for controlling motors up to 1.5 kW, while the FS2, double the width at 90 mm, is designed for ratings from 2.2 to 7.5 kW. At first glance, these devices are the embodiment of simplicity.

Their attractiveness lies in the fact that there are no buttons and operating elements. This makes a simple “out-of-the-box” installation possible, i.e. the installer just has to take the device out of the box, wire it up like a motor starter, and it is already operational. The fact that the DE1 requires no parameter setting means that the probability of installation errors is kept to a minimum and therefore also the time required up to commissioning. Three LEDs indicate the status and operating mode of the unit at a glance. The table provided directly on the device gives a clear explanation of the color coding and flash frequency.

…impressive trip free design at second

Besides simple handling, Eaton has also integrated the aspect of reliability into the new device class. The trip free design of the Variable speed starter (VSS) ensures maximum availability. This concept comprises the ability of the DE1 devices to detect the regenerative energy feedback from the motor and to thus lengthen the ramp automatically. It also includes a DC braking function and the function of automatically reducing the switching frequency to prevent the device temperature from being exceeded. However, in the event that a fault causes the device to switch off, the automatic restart function makes it possible to ensure continuous motor operation. This means that the manual reset of the fault is no longer necessary providing that safety is not impaired.

The benefits of the trip free design are easily demonstrated in practical applications. Imbalance can be a genuine problem in many applications where centrifugal forces are present (e.g. industrial washing machines). On the one hand the motor must accelerate the load, whilst on the other hand, the imbalance mechanically accelerates the motor so that it runs faster than set by the variable frequency drive. This results in regenerative energy feedback into the DC link circuit. Normally the energy must be discharged via a braking resistor. The DE1 offers a refined alternative: An internal algorithm ensures that this does not increase the DC link voltage to impermissible values and thus initiate a shutdown – and all that without the use of a braking resistor.

Fans are another area of application. The air flow in a pipe system can mean that fans often rotate when the driving motor is not switched on. If a speed controller is then required to switch the motor that is already rotating, the controller may be switched off in certain circumstances on account of overcurrent. With these kinds of applications, the DE1 Variable speed starter (VSS) is able to brake the motor with DC current before the motor actually starts in order to prevent the unwanted shutdown. The device therefore ensures fault-free operation even here.

DEFS1

A large market gap

The variable speed starters are factory fitted with internal EMC filters so that they are suitable for use in industrial networks as well as in public utility grids (category C1, C2, C3) without the need for other external EMC filters.

With this unique performance profile and its design for ambient temperatures from -10 to 50 °C (60°C with derating) the Variable speed starter (VSS) meets the demands of several applications on the market for which there was previously no ideal solution. This includes, for instance, applications for which a DOL starter and star-delta starter combination or a soft starter cannot be used since the motor draws a large starting current but does not permit a reduced starting torque. This also applies to materials handling applications, when machines or crushers have to be started up at once under full load after a stop. Even for many simple applications, such as in the field of transport technology, regular variable frequency drives are often overdimensioned, i.e. too elaborate, too expensive and complex.

Many machine builders, who are required to move media such as air or liquids, are now challenged by the requirement of the ErP Directive to design a new drive concept for fans and pumps in order to achieve the prescribed minimum efficiency values. If they have previously used a motor starter and controlled the flow rate mechanically or hydraulically, such as with throttle valves, they are now faced with the challenge of switching to a power-dependent control through the possibility of variable speed adjustment.

The variable speed starter is also ideal for applications requiring a fixed speed that cannot be implemented with the mains frequency. This is often the case in the wood industry where motors are run at high speeds (e.g. 18,000 rpm). The DE1 also offers an alternative where a constant speed is required, but where an IE3 motor cannot be used due to the different mechanical dimensions compared to IE2 motors.

Operation options: Screwdriver to remote keypad

The variable speed starter also offer considerably more options than is seen at first and second glance. A pluggable and universal configuration module, the DX-EXT-SET, enables the operator to change the most important parameters from the factory setting with a screwdriver – without the need for a keypad, software or manual. This means that ramp times, motor protection, mains frequency and terminal configuration can be set ergonomically. Once the parameters have been set via the operating elements on the front, the configuration module can “mechanically store” this parameter set, which can then be transferred directly to other variable speed starters – simply by plugging onto the DE1 device and pressing the Set button. This function simplifies and speeds up commissioning in series production or when replacing a device in the event of a fault.

Eaton also offers users external keypads with LED or OLED displays, already known from the PowerXL series, for an alternative method of parameterizing and operating the DE1, as well as a Bluetooth communication stick for the simple copying of parameters from one device to others. Like all devices of the PowerXL series, the DE1 is also compatible with Eaton’s drivesConnect software. This software and the keypads enable up to 63 devices (DE1, DC1, DA1) to be combined in a drive network and now operate and parameterize them centrally as stations of the network. The DE1 comes with a Modbus interface as standard and can also be integrated directly in Eaton’s innovative SmartWire-DT communication system.

The new PowerXL-DE1 Variable speed starters (VSS) that comply with the international CE, UL, cUL and cTick requirements thus provide machine and system builders with a cost-effective and at the same time highly reliable alternative for worldwide use in order to make applications with a previously constant speed more energy efficient and in compliance with the increasing international legal requirements.

Eaton Corporation, New Plug-In Unit for the NZM3 Circuit-Breaker

Eaton Corporation is offering a new plug-in unit for the NZM3 circuit-breaker. The NZM3 plug-in unit allows customers to exchange the circuit-breaker in a panel simply and quickly, and it also offers benefits during service work because the system section concerned can be disconnected simply and safely.

The housing design of the base has been adapted to that of the NZM3, so that all connection options provided by the main device can also be implemented in the base. For Eaton, safety has the highest priority, and the live parts in the base are therefore automatically protected from direct contact when the circuit-breaker compartment is pulled out. The circuit-breaker also disconnects automatically as soon as the mounting screws are loosened when the circuit-breaker is in the On position or when the circuit-breaker is pushed in. In the latter case, the circuit-breaker can then only be switched on if the mounting screws between the circuit-breaker and the plug-in unit base have been tightened.

Even with the wide range of features and capabilities provided by its products, simple operation and flexibility are top priorities for Eaton: Just fit the modified NZM3 with its rear terminal bolts into the guide, tighten the bolts, and the system is already operational. An auxiliary conductor plug-in device is also available as an option. This enables the connected shunt or undervoltage releases, auxiliary contactors and also the remote operator to be tested without having to fit the circuit-breaker into the panel.  In this way, correct operation can be tested prior to commissioning. Users also do not have to change the wiring when exchanging a circuit-breaker: The auxiliary conductor plug can simply be removed from its base, fitted onto the new terminal cables and operation is restored.

Technical specifications have been set to meet the wide range of requirements in the industrial sector and are impressive in every respect: The new plug-in unit on the NZM3 from 250 – 500A can be used without any derating up to an ambient temperature of 40°C, and this includes the extensive range of accessories. For more demanding applications, the full switching capacity of the NZM3 – up to 150kA at 415VAC – can be used. The circuit-breaker can also be fitted in many positions, either vertically or turned anticlockwise/clockwise by 90°.

The New PowerXL Variable Frequency Drives from Eaton are User-Friendly, Efficient and Robust.

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.
