Choosing the Regenerative Drive
Basically, when choosing the regenerative drive, the power delivered from the drive used to control the motor
is compared to the power that the drive can deliver when overloaded and when operating in continuous
mode, also considering the efficiency of the two drives. In most cases, using two drives of the same model
allows meeting this criterion.
CAUTION
Using two drives (feeder and motor drive) of the same model does not always
meet the criterion above, because the continuous current delivered by the
regenerative drive is sometimes lower than the current delivered by the
equivalent motor drive, as the minimum current frequency for the regenerative
drive is 4 kHz or 5kHz based on the drive model.
It is therefore recommended that the application tables given later in this
section be carefully consulted.
The application tables below for light, standard, heavy, strong applications, contain the model of the drive
that controls the motor and the model of the regenerative drive, depending both on the rated motor voltage
and the mains voltage.
