4-quadrant operation and optional brake chopper
In regenerative operation (4Q braking operation) of the drive, energy is fed into the supply circuit. This may result in an increase of the voltage at the drive and at the output of the 48 V power supply unit.
A DC compound with multiple drives enables efficient energy exchange between different drives in different operating states. The regenerative braking energy of individual drives can be fed back to the other drives and be used for the motoring operation.
You can optionally install a brake chopper with braking resistor as needed to dissipate any unneeded energy as heat.
In addition, there is the option to equip the DC compound with a capacitive energy storage unit.
INFORMATION
- The braking resistor and the brake chopper are not included in the scope of delivery.
- Configure the braking resistor and brake chopper according to the operating instructions. (Observe maximum power loss.)
