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
A reactor 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.
