1. SCOPE
OF
THIS
MANUAL
Elettronica Santerno is committed to update its User Manuals available for download from
the latest software version officially released. Please contact Elettronica Santerno if you require technical
documents related to previous software versions.
2. 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.
Accessory boards are covered in the Motor Drives Accessories Guide.
The parameters shared with the standard Sinus Penta are covered in the Sinus Penta Programming Guide.
The FIRMWARE UPGRADE section explains how to download the files for the Sinus Penta applications to
the standard drive: this download procedure is to be performed only when a drive programmed with standard
firmware,
not
with Regenerative firmware, needs to be updated.
The procedure above is not required if the drive is factory set with the Regenerative firmware.
2.1.
The Rigenerative Application
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 Sinus Penta.
