4.6.4 DC bus coupling
Requirements for DC bus coupling
Device types Only devices of the "HCS01.1E-W00**-*-03" type are suited for DC bus cou‐
pling. DC bus coupling takes place via the optionally available DC bus con‐
nector RLS0778/K06 at the connection point X77 .
Parameterization: For all devices only supplied via the DC bus,
"DC bus → inverter mode" has to be set as the source of power
supply in the parameter "P-0-0860, Converter configuration" (see
also parameter description of the firmware used).
Number A maximum of 8 devices can be coupled at a common DC bus.
Mains connection DC bus coupling is possible for the following types of mains connection:
●
Central supply
● Group supply
DC bus coupling requires:
●
That the Bb contacts of all devices connected to the mains be wired
● That the module bus be wired via all devices at the common DC bus
Central supply and DC bus coupling
Use this type of DC bus coupling if the DC bus continuous power of the in‐
feeding device makes available sufficient power reserves to supply other
HCS01 devices. The devices in the group can be of different types. For the
project planning of the application, observe that the supplying devices can
only make available the DC bus power for other devices which they do not
consume themselves.
With central supply, one HCS01 device charges the DC bus and the other
devices are supplied using DC bus coupling.
Features
●
The supplying device has to be of the HCS01.1E-W0028 or -W0054
type
● Energy compensation between the devices is possible (the DC bus ca‐
pacitors of the devices are connected in parallel)
● Balancing of the integrated braking resistors exists (equal load of all
braking resistors integrated in the devices)
● No balancing measures required in the supply feeder
● To increase the DC bus power, an optional mains choke can be used
● It is possible to connect DC bus capacitor units; DC bus capacitor units
should always be placed directly next to the most powerful device
A DC bus capacitor unit HLC requires a mains choke to be installed
● Small wiring effort for the mains connection
● DC bus short circuit functionality has to be realized externally, if required
