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
socket X200 on the first booksize power unit.
– The DRIVE-CLiQ connections between the power units should each be connected
from the DRIVE-CLiQ sockets X201 to X200 and/or X401 to X400 on the follow-on
component.
Line Modules
● An individual 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 the DRIVE-CLiQ socket X100 is already assigned to a Line Module, the DRIVE-
CLiQ socket X101 should be used.
– Several Motor Modules should be connected in a line.
– If there is already a Line Module present at X100, the Motor Module should be
connected in line to socket X201 of the Line Module.
– 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
in line to socket X201 of the Line Module.
– If there is no Line Module present, the first Motor Module should be connected directly
to the Control Unit (recommended DRIVE-CLiQ socket: X100).
● If the Motor Modules need to be distributed across two DRIVE-CLiQ lines (e.g. on
account of the specified current controller sampling times), the next higher DRIVE-CLiQ
socket on the Control Unit should be used.
● 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, without
routing to additional components.
