SINAMICS S120 Cabinet Modules
Engineering Information
The DRIVE-CLiQ cabling inside a Cabinet Kit is installed at the factory. Cross-component connections, for example,
from the Control Unit of Cabinet Kit >1< to the Motor Module of Cabinet Kit >2< cannot be standardized, as these are
dependent on the configuration and the relevant information is generally not available at the time of ordering.
However, the required cable length can be calculated as being approximately 300 mm from the Control Unit to the
associated power unit + the width of the Booksize Cabinet Kit to be connected. If the power units will be connected in
a "line topology" (power unit to power unit), then the cable length calculation must include the width of the Booksize
Cabinet Kit + at least 100 mm to make allowance for the bending radius and connectors. Please note that this
calculation is valid for connections to the right. For connections to the left, the width of the adjacent Cabinet Kit must
be used in the calculation.
The cables described above for making connections between individual Cabinet Kits must be ordered separately.
Calculation of the DRIVE-CLiQ cable lengths in a Booksize module line-up
Example:
Three Booksize Cabinet Kits are installed in a Booksize Base Cabinet, as illustrated in the diagram above. A
CU320-2 DP Control Unit has been assigned to the second or "middle" kit with option K90. The power unit of the first
Cabinet Kit must be connected to the Control Unit, and the power unit of the third Cabinet Kit must be connected to
the power unit of the second kit.
The required cable lengths are calculated as follows:
1. No additional cable is needed to connect the 2nd power unit (to which the Control Unit is assigned with option
K90), because both components are located in the same Booksize Cabinet Kit and are wired at the factory.
2. The power unit of the first Cabinet Kit requires a cable of at least 300 mm (width of 1st Cabinet Kit) + 300 mm
(distance from 2nd power unit to the associated Control Unit) = 600 mm. According to the catalog, the following
cable must be selected: 6SL3060-4AU00-0AA0, 600 mm in length.
3. The power unit of the third Cabinet Kit requires a cable of at least 200 mm (width of second Cabinet Kit) +
100 mm (bending radius) = 300 mm. According to the catalog, the following cable must be selected: 6SL3060-
4AM00-0AA0, 360 mm in length.
The cables must be secured properly. The maximum permissible bending radius must not be exceeded.
