Lenze 8600 series - Operation with DC-Bus Supply; Connection of Several Drives; DC-Voltage Supply

5.3 Operation with DC-bus supply
5.3.1 Connection of several drives
Drives which are supplied by a three-phase voltage tan also be
linked via the terminals +UG and -UG for energy-sharing. This type
of connection requires all controllers to be supplied simultaneously
with the same mains voltage, with each controller being connected
to the recommended mains Choke.

* The fuses must be dimensioned for the rated output current of the device and a
voltage strength of 1000 V DC.
5.3.2 DC-voltage supply
With direct supply into the DC bus, energy act. value is also
possible. If the drive is in the generator mode (braking), the
absorbed energy will be passed to the DC Source. A brake chopper
is then often not necessary.
