DIMENSIONING THE REGENERATIVE DRIVE
Basically, when dimensioning 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, the drive performances are considered. If two identical drives are used (one as a feeder and one
as a motor controller), failures could occur, because the minimum carrier frequency required for the
regenerative application is 5kHz up to S30 included, and 4kHz for other drive sizes.
The application tables are shown below. Based on the motor power and the type of application (light,
standard, heavy, strong), they contain the size of the drive that controls the motor and the size of the
regenerative drive, depending both on the rated motor voltage and the mains voltage.
