types including high-efficiency IE4 motors such as induction, asynchronous and permanent magnet motors provided by ABB.
earlier direct on line (DOL) power consumption data is given as a benchmark, the drive can calculate the monetary savings and reduced CO2
emissions. The data
generated also makes it easy to estimate the ROI of the power drive. Achieving superior energy efficiency is a job that
is never really finished and ABB’s life cycle services are set up to ensure processes run efficiently year after year. This means complete services are offered, from dimensioning and commissioning, through to eventual replacement with a more efficient drive at the end of the life cycle. The result is continuous efficiency improvements and savings in both energy and operational costs. ABB’s ACS580 drive is highly suited to help
customers meet the new EN50598-2 standards. For the CDM it has the highest IE2 class rating, which means the best efficiency. Data is also available giving losses/ efficiency at several operation points as defined in EN-50598-2. For the new IES classifications for PDS, since ABB
New PDS efficiency classes (IES) for the drive, motor and auxiliaries provide a standardised way to determine system losses via measurements or calculations at standardised operating points.
There are numerous smart functions built into the drive. For example, the energy optimiser features ensure maximum torque per ampere in both scalar and vector control modes, reducing energy drawn from the supply, and providing additional energy savings up to 10% in partial loads. It is also easy to generate accurate reports on hourly and daily energy consumption, as well as the cumulative information. For both financial as well as environmental audits, if

benefits will support customers’ classification and reporting requirements, and also help in prioritising where energy-saving investments should go for improved ROI of the entire operation. l
