Hub Modules

7.1

Description

DRIVE-CLiQ Hub Modules are extension units for star-shaped distribution of a DRIVE-CLiQ line.
Using them, you can extend an axis grouping by 5 DQ interfaces to connect partial axis
groupings. It is possible to connect DRIVE-CLiQ Hub Modules in series (cascade connection).

Safety instructions for Hub Modules

NOTICE
Damage through use of incorrect DRIVE-CLiQ cables
The use of incorrect or unreleased DRIVE-CLiQ cables can cause damage or functional faults to
devices or the system.
• Only use suitable DRIVE-CLiQ cables that have been released by Siemens for the particular
Note
Function equipotential bonding for distributed DRIVE-CLiQ nodes
Integrate all of the components that are connected via DRIVE-CLiQ in the functional
equipotential bonding concept. You make the connection by mounting on bare metallic
machine and plant units that are all connected to one another.
Alternatively, you can establish equipotential bonding with a conductor (min. 6 mm²), which is
routed as far as possible in parallel to the DRIVE-CLiQ cable. This involves all distributed DRIVE-
CLiQ nodes, e.g. DME20, SME20, SME25, SME120, SME125.
Note
Malfunctions due to polluted DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of polluted DRIVE-CLiQ interfaces.
• Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.
