COSMOS DRIVER SERIES 3000 - USE AND MAINTENANCE MANUAL
5.3.4 DC BUS power supply (DC BUS/J3)
The DC BUS power supply is a continuous voltage obtained by rectifying the voltage of the main power supply input; it is
very useful for connecting in parallel several drivers, in order to recover the power produced by the braking motors and
use it for the other motors. Furthermore, it is useful to distribute to different drivers the power dissipated by the dynamic
brake.
CAUTION
It is necessary to strictly adhere to the polarity of the DC BUS power supply, in order to avoid
irreversible damages to the driver.
ATTENTION
La polarité de la connexion de l'alimentation DC BUS doit être scrupuleusement respectée afin de
ne pas risquer des pannes irréversibles de l'entraînement.
