Determination of component cabeling
Only one basic clock cycle can be used within a DRIVE-CLiQ connection. In other words, only combinations of
modules with the same clock cycle or whole multiples thereof may be operated on the same DRIVE-CLiQ connection.
To simplify the configuring process, it is recommended that Line Modules and Motor Modules are supplied by
separate DRIVE-CLiQ connections
The power components are supplied with the required DRIVE-CLiQ connecting cables for connection to the adjacent
DRIVE-CLiQ node within the drive configuration in line topology (not valid for S120 Cabinet Modules). Please follow
the instructions in section "Cable installation". Pre-assembled DRIVE-CLiQ cables in various lengths up to 100 m are
available for connecting motor encoders, direct measuring encoders, Terminal Modules, etc.
The DRIVE-CLiQ cable connections inside the cabinet must not exceed 70 m in length, e.g. connection between the
CU320-2 Control Unit and the first Motor Module or between Motor Modules. The maximum permissible length of
DRIVE-CLiQ MOTION-CONNECT cables to external components is 100 m. Original Siemens DRIVE-CLiQ cables
must always be used. These are designed with special qualities and are the only cable type which can guarantee
fault-free system operation.
The following diagrams show a number of example arrangements and associated DRIVE-CLiQ connections.
