1.5 Rules for wiring with DRIVE-CLiQ

1.5 Rules for wiring with DRIVE-CLiQ
Rules apply for wiring components with DRIVE-CLiQ. A distinction is made between binding
DRIVE-CLiQ rules, which must be unconditionally observed and recommended rules, which
should then be maintained so that the topology, generated offline in STARTER, no longer
has to be changed.
The maximum number of DRIVE-CLiQ components and the possible wiring type depend on
the following factors:
● 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, then 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.
1.5.1

Binding DRIVE-CLiQ rules

The wiring rules below apply to standard cycle times (servo control 125 µs, vector control
250 µs). For cycle times that are shorter than the corresponding standard cycle times,
additional restrictions apply due to the computing power of the Control Unit (configured using
the SIZER configuration tool).
Note
A Double Motor Module, one DMC20, one DME20, one TM54F and one CUA32 each
correspond to two DRIVE-CLiQ participants. This also applies to Double Motor Modules, at
which just one drive is configured.
The following generally binding DRIVE-CLiQ rules must be observed to ensure safe
operation of the drive.
1. A maximum of 14 DRIVE-CLiQ nodes can be connected to one DRIVE-CLiQ line at a
2. A maximum of 8 Motor Modules may be connected to one Control Unit. For multi-axis
3. With vector U/f control, it is only permissible to connect more than 4 participants to one
4. Ring wiring of components is not permitted.
