Operation with DC-bus supply
5.3.1 Connection of several drives
Drives
are supplied by a three-phase voltage
also be
linked via the terminals +UG and -UG for energy-sharing. This type
of connection requires all
to be supplied simultaneously
with the same mains voltage, with
being connected
to the recommended mains
* 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
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
A brake
is then often not necessary.
