12.10 Rules for wiring with DRIVE-CLiQ
● 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.
12.10.1

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 DQ line as Motor Modules.
● The Terminal Modules TM15, TM17 and TM41 have faster sample cycles than the TM31

and TM54F. For this reason, the two groups of Terminal Modules must be connected in
separate DRIVE-CLiQ lines.
