6.4 DRIVE-CLiQ

6.4.1

Basic information

All SINAMICS components communicate with each other via the standardized, internal SINAMICS interface DRIVE-
CLiQ which links the Control Unit to the connected drive objects (.e.g Power Units, Sensor Modules, Terminal
Modules, etc.).
Setpoints and actual values, control commands and status feedback plus the electronic rating plate data of the drive
components or objects are all transferred via DRIVE-CLiQ. Original Siemens DRIVE-CLiQ cables must always be
used. These are designed with special transmission and damping qualities and, as such, are the only cable type
which can guarantee fault-free system operation.
All components linked via one DRIVE-CLiQ connection must operate on the same basic clock cycle. For this reason,
only combinations of components with the same clock cycle or whole multiples thereof may be operated on the same
DRIVE-CLiQ connection (see section "Determination of component cabling"). To simplify the configuring process, it is
advisable to supply Line Modules and Motor Modules via separate DRIVE-CLiQ connections.
Basic rules for connecting SINAMICS components via DRIVE-CLiQ communication
The following basic rules apply to the connections of components via DRIVE-CLiQ:
§ A maximum of 14 nodes can be connected to one DRIVE-CLiQ socket on the Control Unit.
§ A maximum of 8 nodes can be configured in one line. A line always starts at the Control Unit.
§ A maximum of 6 Motor Modules may be configured in a line.
§ A ring wiring is not permitted.
§ A double wiring is not permitted.
§ A maximum of 8 Terminal Modules can be connected.
§ A maximum of 9 motor encoders (Sensor Modules) can be operated on one Control Unit.
In addition, the motor encoders (Sensor Modules) should be connected in each case to the matching Motor Modules.
For further information about DRIVE-CLiQ communication and wiring examples, please refer to the function manual
"SINAMICS S120 Drive Functions".
Note:
It is not possible for several Control Units to communicate with each other via DRIVE-CLiQ, because DRIVE-CLiQ is
an internal SINAMICS interface between the Control Unit and the connected drive objects.
Bus systems like PROFIBUS or PROFINET must be used to provide an external communication between Control
Units, and between Control Units and higher-level controls.
