14.12 System rules, sampling times and DRIVE-CLiQ wiring
● 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, then the SIZER configuring tool should be used to check this topology.
If the real topology does not match the topology created offline using the commissioning tool,
the offline topology must be changed accordingly before it is downloaded.

Binding DRIVE-CLiQ interconnection rules

The following generally binding DRIVE-CLiQ rules must be observed to ensure safe operation
of the drive.
● Only one Control Unit is permitted in the role of DRIVE-CLiQ master in a DRIVE-CLiQ
topology.
● A maximum of 14 DRIVE-CLiQ nodes can be connected to a Control Unit port on a DRIVE-
CLiQ line.
Note
One Double Motor Module, one DMC20, one DME20, one TM54F and one CUA32 each
correspond to two DRIVE-CLiQ nodes. This also applies to Double Motor Modules, at which
just one drive is configured.
● Ring wiring or double wiring of components is not permitted.
● Drive topologies with DRIVE-CLiQ components that are not supported (by the type and the
firmware version of the Control Unit) are not permitted.
● The sampling times (p0115[0] and p4099) of all components that are connected to a DRIVE-
CLiQ line must be divisible by one another with an integer result, or all the sampling times
set for the components must be an integer multiple of a common "base cycle".
– Example 1: A Line Module with 250 µs and Motor Modules with 125 µs can be operated
– Example 2: A Line Module with 250 µs and a Motor Module with 375 µs can be operated
If the current controller sampling time T

solutions are available:
