ABB Drive Browser Software

ABB Drive Browser is an Ethernet network based drive monitoring and tuning PC tool that supports low voltage machinery, general purpose, and industrial drives throughout their life cycle. ABB Drive Browserhelps users monitor, maintain and set drive parameters on drives connected to an Ethernet network.

ABB Drives using an Ethernet adapter can share the same network where PLCs using Modbus/TCP or EtherNet/ IP protocols are connected. This allows users to take advantage of installed networks and reduces additional cabling and infrastructure communication costs. ABB Drive Browser includes a parameter browser allowing users to view and set individual parameter values. Parameter sets that have been saved can be used to commission new drives. Additionally, users can compare parameter sets to quickly identify changes over time or changes in configurations. Drive signals are also displayed in the parameter browser. The monitor functionality enables users to graphically view signals and parameters while the drive is running. Users select the parameters and signals and set the graphs minimum and maximum values. The resulting display shows each selected value on a graph while the drive is operating. This data can be used to tune the drive for improved performance. The collected data can be saved to a file. The ABB drive status window displays the drives current status, showing the drive’s control mode, operation status, output frequency, current, power, speed, and the drive state. Once the installed drives are connected to the network using a fieldbus adapter, users may assign meaningful names to each connected drive and identify drives by type. ABB Drive Browser provides a built-in drive control panel allowing users to reset faults, start, stop, set the direction, and speed reference values of the connected drive. This functionality may be disabled if the controlling PLC does not allow it for networks that are controlled by a PLC.

VFD Speed Controller

VFD Speed Controller

A VFD speed controller is also known as a variable frequency drive, variable speed drive, adjustable frequency drive, VFD or, aninverter.

A VFD speed controller is asolid state electric motor control system, designed to control the speed of an electric motor. A VFD speed controller can reduce energy costsup to 50% by speed reduction on electric motorswhere the full speed of the electric motor is not needed. VFD speed controller functions allow an AC electric motor to only operate when needed, which allows an electric motor to last longer.Technology has allowed VFDs to reduce in cost and physical size, and has improved performance through advances in semiconductor switching devices, simulation, control techniques, control hardware, and software.

Approximately one third of electrical energy in the world is supplied by electric motors in fixed-speed centrifugal pump, fan, and air compressor applications. These fixed-speed applications do not usually require full load speed of the electric motor theyre operating. By installing a VFD speed controller to these applications, electric motor speeds are reduced and power costs can be reduced by 50% or more.Properly applied VFD speed controllers withelectric motorswill also significantly reduce energycosts for variable torque loads such as fans, blowers, and pumps.Blowers are often used with dampers to control air flow that operate either manually or automatically. When dampers are closed, 50% of the electric motor current will drop to approximately 60% of full load nameplate current. By utilizing VFD speed controllersin blower applications, the current draw of the motor will be reduced 30% for every 10% drop in speed. Electric motors controlled by VFD speed controllersat 50% speed will draw approximately 20% of the electric motor full load current.

VFD speed controllersare also used on rotating equipment toreduce amperage spikes upon start up of large electric motors.Adjusting the acceleration and deceleration time of electric motors can extend the lifespan of an electric motor. Using a drive on an electric motor provides the ability to increase or decrease the frequent starting and stopping of an AC electric motor. Limiting the starting and stopping of a motor, and controlling the ramp up and ramp down speed of amotor, allows for decreased wear and extended lifetime of the motor. VFD speed controllers are used in AC servo systems, air compressors, conveyor systems, lathes, mills, plastic extrusion, slitter lines, bottlers, packaging lines, pharmaceutical production, food processing, HVAC systems, waste water treatment systems, submersible pumps, fans, blowers, and many more electric motor applications.

Compressor Speed Control Products – Repair Or Replace?

A compressor speed control is also known as a VFD, variable frequency drive, adjustable speed drive,or an inverter. To repair the compressor speed control, unique experience and training are needed. Repairing a compressor speed control should be taken with extreme caution. Alwaysconsult an expert in the field when repairing or troubleshooting industrial electrical equipment. Most compressor speed controls have an internal DC bus that retains a charge after power has been cut to the drive, and as a result, the power being cut doesn’t mean that the equipmentissafe to work with. Technicians working with a compressor speed control and other electrical equipmentmust always take extra precautions to ensure proper safety measures are taken to prevent injury or death.

Compressor Speed Control, Repair Or Replace?

Compressor speed control repair services are an assetfor Sullair service centers and other manufacturers. In most cases, the replacement of a speed control is more expensive and more time consuming than a repair. The extent of damage present in a compressor speed control will determine whether or not the equipment can be repaired. The speed control must be tested, disassembled, and inspected thoroughly by trained technicians to diagnose the cause of failure and determine repair cost.

Most companies who offer repair services for speed control products, outsource the repair to third party repair centers. Then, the service center offering this repair service, will mark up the cost for being the “middle man”. Precision Electric performs these repairs for third parties every day. Sometimes the speed control manufacturer also offers repair services but then once they have the speed control in their possession, they tell the customer that the speed control cannot be repaired and needs to be replaced. Precision Electric repairs compressor speed control products all the time after manufacturers have deemed the equipment “not worth repair” or“needs to be replaced”.

Eaton Cutler Hammer, for example, is a manufacturer of speed control products, that offers VFD repair services for their products. Sending the speed control to Eaton for repair isn’t the most economical solutionbecause Eaton has extensive lead times for repairs, and Eaton almost always ends up recommending replacing the entire speed control.Precision Electric offerscomplete Eatonspeed control repair and all repairs are performed in house, at Precision Electric.

Over the past decadeVFDtechnology has become a cost efficient way to reduce power costs and increase system efficiency. Manufacturers within a wide range of industries are finding more ways to apply VFD’s to their rotating equipment.From past experience, smaller horsepower VFD’s typically fail in eight years and are more often replaced rather than repaired.Larger horsepower VFD’s last longer by virtue of repairs that often require replacement of circuit boards and other electrical components.
