SINAMICS S120
Engineering Information
Specification of component cabling
All the modules linked via one DRIVE-CLiQ connection must operate on the same current controller clock cycle. For
this reason, only combinations of modules with the same current controller clock cycle can be operated in the same
DRIVE-CLiQ connection. To simplify the configuring process, it is advisable to supply Line Modules and Motor
Modules via separate DRIVE-CLiQ lines.
The power components are supplied with the required DRIVE-CLiQ connecting cables for connection to the adjacent
DRIVE-CLiQ node in the axis grouping (line topology) (not applicable to 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 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.
