12.10 Rules for wiring with DRIVE-CLiQ

12.10 Rules for wiring with DRIVE-CLiQ
The following rules apply for wiring components with DRIVE-CLiQ. The rules are subdivided
into DRIVE-CLiQ rules, which must be observed, and recommended rules, which, when
observed, do not require any subsequent changes to the topology created offline in
STARTER.
The maximum number of DRIVE-CLiQ components and the possible wiring form depend on
the following points:
● The binding DRIVE-CLiQ wiring rules
● The number and type of activated drives and functions on the Control Unit in question
● The computing power of the Control Unit in question
● The set processing and communication cycles
Below you will find the binding wiring rules and some other recommendations as well as a
few sample topologies for DRIVE-CLiQ wiring.
The components used in these examples can be removed, replaced with others or
supplemented. If components are replaced by another type or additional components are
added, the SIZER tool should be used to check the topology.
If the actual topology does not match the topology created offline by STARTER, the offline
topology must be changed accordingly before it is downloaded.

General rules

DRIVE-CLiQ rules
The wiring rules below apply to standard cycle times (servo 125 µs, vector 400 µs). For cycle
times that are shorter than the corresponding standard cycle times, additional restrictions
apply due to the computing power of the CU (configuration via the SIZER tool).
The rules below apply on a general basis, unless limited, as a function of the firmware
version.
Note
A Double Motor Module, a DMC20, a TM54F and a CUA32 each correspond to two DRIVE-
CLiQ participants. This also applies to Double Motor Modules, of which just one drive is
configured.
● A maximum of 14 nodes can be connected to a DRIVE-CLiQ line on the Control Unit.
● Up to 8 nodes can be connected in a row. A row is always seen from the perspective of
● Ring wiring is not permitted.
● Components must not be double-wired.
● The TM54F must not be operated on the same DRIVE-CLiQ line as Motor Modules.
