12.10 Rules for wiring with DRIVE-CLiQ
● If a CU link connection is detected, the DRIVE-CLiQ basic clock cycle 0 (r0110[0]) is set
● The following applies for booksize format:
● The following applies for chassis format:
● Parallel operation of power units in chassis format:
● For a parallel connection of Motor Modules, only one motor with integrated DRIVE-CLiQ
● Switchover between different motors is not permitted for a parallel connection.
● Mixed operation of Infeed Modules or Motor Modules:
● Mixed operation of formats:

to 125 μs and assigned to this DRIVE-CLiQ socket.
– In the servo control, vector control and U/f control operating modes, only one Line
Module may be connected to the Control Unit.
– It is permissible that one Line Module and Motor Modules are connected together to
one DRIVE-CLiQ line in servo control.
– One Line Module and Motor Modules must be connected to separate DRIVE-CLiQ
lines in vector control.
– For booksize format, a parallel connection of Line Modules or Motor Modules is not
possible.
– Line Modules (Active Line, Basic Line, Smart Line) and Motor Modules must be
connected to separate DRIVE-CLiQ lines.
– A parallel connection of Infeed Modules as well as Motor Modules is only permitted for
vector control or for V/f control.
– A maximum of 4 Infeed Modules are permissible within a parallel connection.
– A maximum of 4 Motor Modules are permissible within a parallel connection.
– Precisely one parallel connection of Motor Modules is permitted. For a parallel
connection, precisely one drive object is created in the topology.
interface (SINAMICS Sensor Module Integrated) is permitted for each Motor Module.
– The operation of Infeed Modules or Motor Modules with different performance values
is not permitted within a parallel connection.
– For Line Modules in chassis format, two parallel connections are permissible for mixed
operation of Smart Line Modules and Basic Line Modules.
– The following combinations of Line Modules are not permissible:
Active Line Module (ALM) with Basic Line Module (BLM)
Active Line Module (ALM) with Smart Line Module (SLM)
– Combining small power units (400V; >250kW) and large power units (500 - 690V) to a
DriveCLiQ line results in current derating as a result of the pulse frequency adaptation.
Chassis Motor Modules and booksize Motor Modules must therefore be connected to
separate DRIVE-CLiQ lines.
