Hub properties

DRIVE‑CLiQ hub characteristics
The DMC20 and DME20 DRIVE‑CLiQ hub modules are used to implement point-to-point
distribution of a DRIVE‑CLiQ line. With the DMC20/DME20, an axis grouping can be expanded
with 4 DRIVE‑CLiQ sockets for additional subgroups.
● DMC20 is the hub for the control cabinet configuration
● DME20 is the hub for use without a control cabinet (IP67 degree of protection).
The modules are especially suitable for applications which require DRIVE‑CLiQ nodes to be
removed in groups, without interrupting the DRIVE‑CLiQ line and therefore the data exchange.
Application examples
Typical applications of DRIVE‑CLiQ hubs are encoder expansion and hot plugging.
● In an encoder expansion, direct measuring systems are connected. For example, these
are attached directly to the machine in the control cabinet. Several encoders can be
connected to one hub in the cabinet.
● Hot plugging is the option for changing Motor Modules while in operation. To do so, the
Motor Modules are connected via a DRIVE‑CLiQ hub in the form of a point-to-point
topology. This means they can be deactivated without impairing downstream components
(via cascading).
Note
Cascading is permitted one time only (from hub to hub).
Connection conditions for ENCODER drive objects
● All encoders that can be assigned to a drive can be used.
● ENCODER drive objects may be connected to all DRIVE-CLiQ ports.
● Up to 4 DRIVE-CLiQ HUBs (DMC20 or DME20) can be used to establish a star-shaped
wiring of the ENCODER drive objects. This means that a maximum of 19 possible
ENCODER drive objects can be connected to one Control Unit. This means that the number
of possible ENCODER drive objects is restricted so that a total maximum of 24 drive objects
can be connected to one Control Unit.
● The DRIVE-CLiQ HUBs must be directly connected to the Control Unit.
