ABB launches standard drive for easy installation and use

ABB Limited (Group Headquarters) : 28 October, 2005  (New Product)
A new range of intuitive, standard drives, designed to be sold off-the-shelf with few optional extras, has been launched by ABB. ABB
The product has a range of innovative user support features, making it”the easiest drive to install, commission and use” according to James Haigh, senior vice president, drives, at ABB.

Included is a start-up assistant that guides users through all essential settings without the need to access complex parameter lists. If a fault occurs, simply pressing the”help” button will suggest ways to fix the fault.

A total of nine different predefined settings are available, covering the vast majority of industrial applications. If a parameter needs to be altered for the application, this can be done easily. It is also possible to set up the application manually.

A maintenance assistant keeps track of the running time and gives a signal when maintenance is required, while a real time clock and calendar enables the user to cycle events according to the time of day, week or month.

All the functions are accessed through a new development in control panel technology. The control panel is similar in look and functionality to a mobile phone and features two soft keys, the function of which changes according to the state of the panel. A built-in help button and a real-time clock assist in fault diagnosis. This enables easy commissioning, fast set-up, simple configuration and rapid fault diagnosis.

The harmonic signature of the drive has been reduced by patent pending; swinging DC chokes that suppress harmonics caused by the inverter so that the percentage of total harmonic distortion goes down when the load is reduced. Normally, total harmonic distortion increases when the load is reduced. This is because the impedance of a standard DC choke is optimised for a specific throughput, normally that used at full load. ABB’s swinging choke, in contrast, features a variable air gap, giving flexible impedance for a range of different load conditions.
