Binding Drive-Cliq Interconnection Rules - Siemens Sinamics S120 Comissioning Manual

Appendix
A.4 System rules, sampling times and 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.4.4.1

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 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 corresponds to 2 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".
