DRIVE CLiQ

Basic informations

All SINAMICS components communicate with one another via the standardized DRIVE CLiQ interface. This interface
connects a Control Unit with the power components, encoders and other system components such as terminal
modules.
Setpoints and actual values, control commands, status messages and rating plate data of the components are
transferred via DRIVE CLiQ.
Only one current controller clock cycle can be set for modules connected via DRIVE-CLiQ. In consequence, only
combinations with an identical current controller clock cycle can be operated on the same DRIVE-CLiQ connection
(see tables in the sections "Specification of the required control performance and selection of the Control Unit" and
"Specification of component cabling"). To simplify the configuring process, it is advisable to supply the Line Modules
and Motor Modules via separate DRIVE-CLiQ connections.
Wiring of DRIVE-CLiQ components
The following rules apply to the wiring of components with DRIVE-CLiQ:
•
A maximum of 16 nodes can be connected to a DRIVE-CLiQ socket on the CU320 Control Unit
•
A maximum of 8 nodes can be configured in one line. A line always starts at the Control Unit.
•
Maximum 6 Motor Modules in one line
•
Ring wiring is not permitted
•
Components must not be double-wired.
In addition, the motor encoder should be connected to the associated Motor Module.
Control Units cannot communicate with one another via DRIVE-CLiQ.

DRIVE-CLiQ cables supplied with the unit

Buit-in units are supplied as standard with DRIVE-CLiQ cables. Their length is tailored to the requirements of the
relevant module. This guarantees that the delivered components can be assembled into a functional unit with these
standard cables.
However, the cable lengths are suitable only for standard configurations. The lengths which may be required for
specific applications must be calculated at the configuring stage and ordered separately if necessary. Only cables
adapted to the given ambient conditions must be used. Information can be found in the SINAMICS catalogs.
