If possible, place the DC bus capacitor unit directly next to the drive controller
to be supplied or the most powerful drive controller. Connect the DC bus ca‐
pacitor unit to the drive controller via the DC bus connection X77.

Module bus and parameterization
Module bus
The module bus is an internal system connection. To ensure the coordinated
behavior of all devices of a drive system, the devices have to exchange infor‐
mation via the module bus.
With the parameter "P-0-0118, Power supply, configuration", both a common
error reaction for all axes and power off in the case of error can be parame‐
terized.
If several devices are coupled via the DC bus, it is mandatory to
loop through the module bus.
Use shielded lines to loop through the module bus, if the length of
all module bus connections is greater than 3 m. See
Module bus cable shield connection" on page 256
.

Looping through the module bus
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, Convert‐
er configuration".
For detailed information, see the documentation of the firmware used:

Bb relay contact
Generally, the following applies: Include the Bb contact in the mains contac‐
tor circuit at all devices connected to the mains. (See also
Circuit for the Mains Connection" on page 104
)
If several devices supply the DC bus (group supply), connect the Bb relay
contacts (X47) of all supplying devices in series. This guarantees that the
mains contactor is switched off in the case of error in a device.
For devices which are only supplied via the DC bus, it is sufficient that you
establish the module bus connection. You do not need to connect the Bb re‐
lay contacts of these devices in series.
