ABB VFD ACS550 Packaged Systems

The ACS550-CC is a packaged version of the ACS550 series. Itis a complete drive with bypass package that includes the ACS550 VFD, a bypass function that allows the motor to be run at full voltage (in the event the drive is shut down for service), a main disconnect, branch circuit, short circuit and ground fault protection. Complete ACS550 systems are pre-engineered packaged systems that reduce time, effort and the cost of installation. The ACS550-CC bypass function is configured entirely of standard industrial control components. The ACS550-CC bypass package includes two electrically interlocked contactors, a motor overload relay, a control power transformer with primary and secondary fusing, and a cover mounted drive-off bypass selector switch. The ACS550-CC bypass is accomplished by means of the two contactors. One is the bypass contactor used to connect the motor directly to the power line. The second contactor is the output that disconnects the motor from t he drive output when operating in bypass mode. This prevents the back feeding that would occur if line voltage were applied to the drive output terminals. The ACS550-CC output contactor and the bypass contactor are electrically interlocked to prevent simultaneous operation.

ABB DTC

/4 Comments/in , /by

ABB DTC or Direct Torque Control, is the most advanced AC drive technology developed by any drive manufacturer in the world.With the revolutionary ABB DTC technology, field orientation is achieved without feedback using advanced motor theory to calculate the motor torque directly and without using modulation. The controlling variables are motor magnetising flux and motor torque. With ABB DTC, there is no modulator and no requirement for a tachometer or position encoder to feed back the speed or position of the motor shaft. ABB DTC uses the fastest digital signal processing hardware available and a more advanced mathematical understanding of how a motor works. The result is a drive with a torque response that is typically 10 times faster than any AC or DC drive. The dynamic speed accuracy of ABB DTC drives will be 8 times better than any open loop AC drives and comparable to a DC drive that is using feedback. ABB DTC produces the first universal drive with the capability to perform like either an AC or DC drive.

There are many benefits of ABB DTC technology. But most significantly, drives using ABB DTC technology have the following exceptional dynamic performance features, many of which are obtained without the need for an encoder or tachometer to monitor shaft position or speed: Torque response: How quickly the drive output can reach the specified value when a nominal 100 percent torque reference step is applied. For DTC, a typical torque response is 1 to 2 ms below 40 Hz compared to between 10-20 ms for both flux vector and DC drives fitted with an encoder. With open loop PWM drives,the response time is typically well over 100 ms. With its torque response, ABB DTC has achieved the natural limit. With the voltage and current available, response time cannot be any shorter. Even in the newer sensorless drives the torque response is hundreds of milliseconds. Accurate torque control at low frequencies, as well as full load torque at zero speed without the need for a feedback device such as an encoder or tachometer. With ABB DTC, speed can be controlled to frequencies below 0.5 Hz and still provide 100 percent torque right the way through to zero speed. Torque repeatability:How well the drive repeats its output torque with the same torque reference command. ABB DTC, without an encoder, can provide 1 to 2 percent torque repeatability of the nominal torque across the speed range. This is half that of other open-loop AC drives and equal to that of closed-loop AC and DC drives.

Motor static speed accuracy:Error between speed reference and actual value at constant load. For ABB DTC, speed accuracy is 10 percent of the motor slip, which with an 11 kW motor, equals 0.3 percent static speed accuracy. With a 110 kW motor, speed accuracy is 0.1 percent without encoder (open-loop). This satisfies the accuracy requirement or 95 percent of industrial drives applications. For the same accuracy from DC drives an encoder is needed. In contrast, with frequency controlled PWM drives, the static speed accuracy is typically between 1 to 3 percent. So the potential for customer process improvements is significantly higher with standard drives using ABB DTC technology. An ABB DTC drive using an encoder with 1024 pulses/revolution can achieve a speed accuracy of 0.01 percent. Dynamic speed accuracy:Time integral of speed deviation when a nominal (100 percent) torque speed is applied. ABB DTC open-loop dynamic speed accuracy is between 0.3 to 0.4%sec. This depends on the gain adjustment of the controller, which can be tuned to the process requirements. With other open-loop AC drives, the dynamic accuracy is eight times less and in practical terms around 3%sec.If we furnish the ABB DTC controller with an encoder, the dynamic speed accuracy will be 0.1%sec, which matches servo drive performance.

Standard applications account for 70 percent of all variable speed drives installed throughout industry. Two of the most common applications are in fans and pumps in industries like heating, ventilating and air conditioning (HVAC), water and food and drinks. In these applications, ABB DTC provides solutions to problems like harmonics and noise. For example, ABB DTC technology can provide control to the drive input line generating unit, where a conventional diode bridge is replaced with a controlled bridge. This means that harmonics can be significantly reduced with a DTC controlled input bridge. The low level current distortion with an ABB DTC controlled bridge will be less than a conventional 6-pulse or 12-pulse configuration and power factor can be as high as 0.99. For standard applications, ABB DTC drives easily withstand huge and sudden load torques caused by rapid changes in the process, without any overvoltage or overcurrent trip. Also, if there is a loss of input power for a short time, the drive must remain energised. The DC link voltage must not drop below the lowest control level of 80 percent. To ensure this, DTC has a 25 microseconds control cycle.

There are vast differences between ABB DTC and many of the sensorless drives. But the main difference is that ABB DTC provides accurate control even at low speeds and down to zero speed without encoder feedback. At low frequencies the nominal torque step can be increased in less than 1ms. This is the best available, because the motor is now the limit of performance and not the drive itself. A typical dynamic speed accuracy for a servo drive is 0.1%s. An ABB DTC drive can reach this dynamic accuracy with the optional speed feedback from a tachometer. The most striking difference is the sheer speed by which ABB DTC operates. As mentioned above, the torque response is the quickest available. To achieve a fast torque loop, ABB has utilised the latest high speed signal processing technology and spent 100 man years developing the highly advanced motor model which precisely simulates the actual motor parameters within the controller.

plastic injection molding and manufacturing

Injection Molding

/1 Comment/in , /by

Injection moldingis amanufacturingprocess for producing parts by injecting material into a mold. Injection molding can be performed with metals,glasses, confections, andplastic thermoforming. Material for injection molding parts is fed into a heated barrel, mixed, and then forced into a mold cavity where it cools and hardens to the specifications of the cavity.

After an engineer designs a product, molds are made by a toolmaker from steel or aluminum. After the mold is made it is precision machined to form the features of the desired part. Injection molding is used for manufacturing a variety of parts, from small components to body panels for automobiles. Technology advances in3D printing using photo polymers can also be used for some simple injection molds. Photo polymers are used because they do not melt during the injection molding of some lower temperature plastic thermoforming processes.

Injection molding parts must be carefully designed to facilitate the molding process to prevent defective parts manufacturing. The material used for the part, shape, features, mold material, and the properties of the molding machine must all be taken into consideration. The versatility of injection molding is facilitated by this compass of design considerations and possibilities.

Injection molding uses a ram or screw type plunger to force molten plastic material into a mold cavity. The material then solidifies into a shape that has conformed to the design of the mold. Injection molding is most commonly used to process plastic thermoforming in terms of total annual material volumes processed. Plastic thermoforming is prevalent because its characteristics make them highly suitable for injection molding; such as the ease with which they may be recycled, versatility allowing them to be used in a wide variety of applications,and their ability to soften and flow upon heating. Plastic thermoforming is also much safer than thermosetting because if a thermosetting polymer is not ejected from the injection barrel in a timely manner,chemical crosslinkingmay occur causing the screw and check valves to quit performing and potentially damaging the injection molding machine.

All injection molding processes can produce flawed parts. Troubleshooting is performed by examining defective parts for specific defects and addressing these defects with the design of the mould or the mold characteristics. Tests are performed before full production cycles begin in an effort to predict defects and determine the appropriate specifications to use in the injection process.

Harmonic Distortion

/in , , /by

Harmonic Distortion is any distorted voltage and current waveform that deviates from an ideal sinusoidal waveform. Harmonic distortion presents potential harm and equipment downtime to electrical components. Non-linearloads connected to the electrical supply in facilities cause harmonics (waveform distortions) on the power distribution system. Common non-linear loads include solid state motor soft starters, variable frequencydrives, computers, electronic lighting, welding supplies and uninterrupted power supplies.

The Institute of Electrical and Electronics Engineers (IEEE) has established a recommended practice – IEEE 519-2014- which sets limits for harmonic current and voltage distortion for electrical power systems.This recommended practice provides the foundation for evaluating the level of harmonic distortion in a power distribution system, and the level of action required to mitigate the risks.Industries such as water and waste water treatment, and HVAC, must meet local requirements to achieve low harmonic levels; this prevents disturbances to equipment in nearby residential properties and commercial buildings.Harmonic distortion can impact a system in many ways: it can cause distribution transformers to overheat, resulting in insulation breakdown and failure; electronic displays and lighting may flicker; nuisance tripping of circuit breakers is possible; and damage can occur to electronic equipment. Harmonic distortion effects are not limited to the facilities where electrical equipment is installed. This potentially impacts any residential and commercial areas, where electrical equipment is installed such as: pumping stations, waste water treatment plants, cooling towers and HVAC systems.

Harmonic Distortion Reduction

Professionals responsible for designing and maintaining electrical systems must be aware of the potential issues related to harmonic distortion of their power distribution systems; and know how to manage them in the most efficient and cost effective manner.Many factors and components impact the overall quality of a power distribution system. Variable frequency drives (VFD’s) are among the many electrical devices included in that group. Manufacturers of variablefrequency drives offer a variety of answers to the question of how to reduce the levelof distortion these devices produce. Most of these solutions involve adding large, costly components like specialty transformers to the variable frequency drive installation to reduce the level of harmonic distortion.

ABB offers a broad range of Ultra Low Harmonic drive solutions. ABB ULH drives have built-in components to reduce harmonic distortion. ABB ULH drive solutions provide the best combination of harmonic reduction, package size, weight and range of features.The ABB Ultra-low Harmonic drive solution provides the best overall management of harmonic distortion of all solutions tested. Not only are the current and voltage distortions minimized, but the power factor is controlled to operate at unity (1.0), minimizing the total current used by the drive. ABBULH drives are the ideal solution for those drive installations where low harmonic content is desired or mandated. Its footprint is generally smaller than com parable stand-alone installations that use additional bolt-on harmonic reduction means. Its performance and simplicity of installation make it suitable for the water and wastewater industry, which includes applications such as: pumps, blowers, and compressors.

acs550We’re pleased to announce the addition of ACS550 Series Variable Frequency Drives to our online sales product line. The ACS550 Drives is a long time player from the line of ABB variable frequency drives and go up to 550 horsepower. This drive is a great fit for users who are used to the ABB brand of variable frequency drives and are looking for a cost-effective solution for running their motor application.

The ABB ACS550 Series drive finds it’s place as a mid-level applications drive. Typically it is used for open loop applications rather than closed loop. There is an optional encoder card though for users who find themselves in need of a closed loop setup of their motor and drive.

As with the majority of variable frequency drives out there, such as the SMVector, the ACS550 also comes with threeoperating modes. These operating modes include standard V / Hz control, variable torque controlandopen loop vector control. An integrated line filter (or EMC filter) comes standard onany model in an R2 frame or smaller. All boards are coated for harsh environments and each ACS550 includes a swinging choke for superior harmonic reduction.

If you find yourself wanting to know more information on the ACS550 drive simply swing by anyACS550 product page to learn more, you can also grab the manuals while you’re there to get an idea of how to setup your drive. One of the unique features of all ABB drives is the macro system for setting up applications, such as pumps or fans. Each drive comes with preset macros that make the configuration and startup the drive simple.

One confusing aspect of ABB drives is that they tend to come in two separate ratings. There is a “standard rating” and a “heavy duty rating” – heavy duty ratings are typically reserved for applications that are variable torque and may endure extreme loads for up to 10 minutes. To be exact, the ACS550 heavy duty ratings allow for 150% short term overload ratings from 1 to 10 minutes. Since we aren’t always able to know the application our customers are implementing these drives into all ratings at our site are specified at heavy duty.

The ACS800 variable frequency drive is a newer product for those looking for a possible replacement or upgrade of their ACS550 drive. The ACS800 is defined by us as an applications drive. This drive has just about every feature a modern variable frequency drive can have. This includes the integration of a full range of applications and extensive quantity of accessories to make it compatible with almost any industrial system. For the longest time the ACS800 has been ABBs go to drive.
