The UNI2403 and UNI2403-r configuration process is a relatively simple setup process that should be able to get you back up and running with minimal downtime.

With some simple UNI2403 11kw configuration the drive can be used as an AC Regenerative Unit, also known as a Regen Drive. In the case of a drive operating in Regen mode, the IGBT bridge is used as a sinusoidal rectifier, which converts the AC supply to a controlled DC voltage. This DC voltage can then be used to supply one or more Unidrives which control motors, commonly known as motoring drives.

A regen drive produces PWM output voltage which has a sinusoidal fundamental at an amplitude and phase which are almost the same as those of the AC supply voltage. The difference between the drive PWM line voltage and the supply voltage occurs across the Regen drive’s inductors.

There are a number of possible options available when designing a Unidrive Regen system depending on the user requirements and the nature of the AC supply. Non standard systems can be created where favourable supply conditions exist, allowing cost and space savings to be achieved by reducing the number of components.

A Unidrive can be used as a sinusoidal input current power unit to supply one or more Unidrives via their DC buses. When this mode is selected as the drive type, menu 15 appears. This menu is used to set up the Unidrive. At the same time, menu 0 defaults to showing Pr 15.01 to Pr 15.13 as Pr0.11 to Pr 0.28.
