DC bus connecting bar
Fig. 4-36:
DC bus connection via connecting bar
Via a "spur line", the DC buses of the individual devices are connected to the
DC bus connecting bar.
The power reserve of the supplying devices limits the number of devices at
the common DC bus.
DC Bus Capacitor Unit
Function
DC bus capacitor units are optional additional components and increase
●
the DC bus continuous power
●
the available DC bus energy
Mains Choke
Always operate the DC bus capacitor units together with the mains choke as‐
signed to the drive controller (see
chapter 7.3.2 "Mains voltage" on page
Special case "HCS01.1E-W0018-_-03" (in the technical data, no mains choke
has been assigned to this drive controller):
Use the mains choke "HNL01.1E-1000-N0012-A-500-NNNN".
Connection
The maximum allowed capacitance of a DC bus capacitor unit depends on
the device which assumes the DC bus supply.
Even if several devices supply the DC bus, the specific external
DC bus capacitance of the biggest supplying device may only be
connected once for the entire DC bus group!
For the maximum allowed external DC bus capacitance at
U

, see the technical data (
chapter 7.3.3 "DC bus" on page
).
