OVERVIEW
Special software that can be used for particular applications is supplied with the drives of the Sinus Penta
series. The menu tree, the programming mode and navigation mode of the Sinus Penta are used; parameters
or menus will be added/(removed) whether required/(not required) for your application.
This manual covers the wiring diagrams and the parameters relating to the Regenerative application; for any
detail concerning option control boards and parameters common to the Sinus Penta, please refer to the Sinus
Penta’s Installation Instructions and Programming Instructions manuals.
Download of the application files for the standard Penta drive is detailed on the last pages of this manual.
Download, however, is not normally required, because the drive is already factory-set for the Regenerative
application.
1.1.
THE REGENERATIVE APPLICATON
The Regenerative Penta drive allows exchanging ingoing-outgoing power with sinusoidal currents (weak
current harmonics) and with a unitary power factor. The Regenerative application allows tuning the DC-bus
voltage: when the Penta is used to power one or multiple inverters for motor control, this allows recovering the
kinetic energy of the connected motor(s) during the braking stage, and delivering energy to the mains (thus
avoiding using braking resistors, which also cause overheating). When the motor drive is powered by the DC-
bus through the regenerative function, motors having greater voltage ratings than the mains voltage can be
controlled by the Penta.
Also, the regenerative drive can be used as a braking unit.
