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 the commissioning tool,
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 configuring tool should be used to check this topology.
If the actual topology does not match the topology created offline using the commissioning
tool, the offline topology must be changed accordingly before it is downloaded.
A.5.4.1
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 permissible 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 corresponds to 2 DRIVE
-CLiQ nodes. This also applies to
Double Motor Modu
les, at which just one drive is configured.
● Ring wiring or double wiring of components is not permitted.
