IEEE P1566/D2, Oct 2014

IEEE P1566/D2, Oct 2014 is an IEEE draft standard focused on the performance of adjustable speed AC drives rated 375 kW and larger. It addresses a high-power drive class used in industrial power, energy, and equipment systems where controlled motor speed and dependable operation are important. For engineering, procurement, and testing teams, this draft helps define how such drives should be evaluated and compared, supporting more consistent specifications for large-scale applications.

Overview of IEEE P1566/D2, Oct 2014

IEEE P1566/D2, Oct 2014 provides technical direction for assessing the performance of large adjustable speed AC drives, particularly those at 375 kW and above. In this context, performance may include operating behavior, controllability, and suitability for demanding drive applications. As a draft document, it is relevant to users who need a clear framework for design review, test planning, or specification work involving high-capacity AC drive equipment within power, energy, and industrial systems.

Typical use cases

This standard is typically relevant when specifying or evaluating high-power adjustable speed AC drives for heavy industrial machinery, large pumps, compressors, conveyors, or process equipment. It may also be used in engineering workflows that compare drive performance across projects or suppliers. Because the scope begins at 375 kW and larger, it is especially useful for applications where motor control, operating stability, and repeatable performance are central to system design and acceptance.

Why it matters

For large AC drive installations, even small differences in performance can affect uptime, process control, and equipment stress. IEEE P1566/D2, Oct 2014 helps create a more consistent basis for review and testing, which can reduce ambiguity during procurement and commissioning. It also supports better alignment between design expectations and actual drive behavior, making it easier to manage compliance, compare technical offers, and limit risk in high-value industrial applications.
