Control Units without infeed control

Description
To ensure that the drive line-up functions satisfactorily, you must ensure – among other
things – that the drives only draw power from the DC link when the infeed is in operation. In a
DC link line-up that is controlled by just one Control Unit and in which a drive object has an
infeed, the BICO interconnection p0864 = p0863.0 is established automatically during
commissioning.
In the following cases, the BICO input p0864 must be supplied manually:
● Smart Line Modules without DRIVE-CLiQ (5 kW and 10 kW)
● DC link line-up with more than one Control Unit
Examples: interconnecting "Infeed ready"
Smart Line Modules without DRIVE-CLiQ (5 kW and 10 kW)
Figure 11-10 Example: interconnecting a Smart Line Module without DRIVE-CLiQ
DC link line-up with more than one Control Unit
In the following example, two Control Units control drives that are connected to the same DC
link. The source for the "Infeed operation" signal can also be a digital input.
