Figure 2 shows the block-diagram for the connection of a SINUS PENTA used as a regenerative feeder
powering a SINUS PENTA used as a motor controller.
Figure 2: Block-diagram of the regenerative drive.
An inductance filtering PWM voltage from the output terminals of the drive and transforming output current
into sinusoidal current is to be installed between the regenerative drive and the mains.
Using the drive as a regenerative feeder is particularly useful when the motor connected to the drive frequently
operates as a generator (e.g. lifting applications, test benches, etc.). Energy is then delivered to the mains
under a sinusoidal waveform and with a unitary power factor, thus ensuring energy saving and avoiding using
braking resistor units.
NOTE
Output power is intended for the supply of one or more SINUS K inverters/PENTA
drives. Any other applications must be authorized by Elettronica Santerno.
