Recommended Interconnection Rules - Siemens SINAMICS S120 Function Manual

13.12.4.2

Recommended interconnection rules

The following recommended rules should be observed for the DRIVE-CLiQ wiring:
General
● The following applies to all DRIVE-CLiQ components with the exception of the Control
Unit: The DRIVE-CLiQ sockets Xx00 are DRIVE-CLiQ inputs (Uplink), the other DRIVE-
CLiQ sockets are outputs (Downlink).
– The DRIVE-CLiQ cable from the Control Unit should be connected to DRIVE-CLiQ
– The DRIVE-CLiQ connections between the power units should each be connected
Line Modules
● A single Line Module should be connected directly to the Control Unit (recommended
DRIVE-CLiQ socket: X100).
– Several Line Modules should be connected in series.
Motor Modules
● No more than 6 Motor Modules should be connected to a DRIVE-CLiQ line on the Control
Unit (including with vector, V/f control).
● Motor Modules should be connected directly to the Control Unit in vector control.
– If DRIVE-CLiQ socket X100 is already assigned to a Line Module, DRIVE-CLiQ socket
– Several Motor Modules should be connected in a line.
● In servo control, Motor Modules should be connected to a DRIVE-CLiQ line together with
the Line Module.
– Several Motor Modules should be connected in a line.
– If there is already a Line Module present, the first Motor Module should be connected
– If there is no Line Module present, the first Motor Module should be connected directly
● If the Motor Modules need to be distributed across two DRIVE-CLiQ lines (e.g. on
account of the predetermined current controller sampling times), the next higher DRIVE-
CLiQ socket on the Control Unit should be used.
Example, vector control in the chassis format:
– Active Line Module current controller sampling time 400 µs: X100
– Motor Modules current controller sampling time 250 µs: X101
– Motor Modules current controller sampling time 400 µs: X102
● Only one end node should be connected to free DRIVE-CLiQ sockets within a DRIVE-
CLiQ line (e.g. Motor Modules wired in a line), for example, one Sensor Module or one
Terminal Module, without routing to additional components.
