General Rules - Siemens SINAMICS S120 Commissioning Manual

1.5.1

General rules

DRIVE-CLiQ rules
The wiring rules below apply to standard cycle times (servo 125 µs, vector 400 µs). For cycle
times that are shorter than the corresponding standard cycle times, additional restrictions
apply due to the computing power of the CU (configuration via the SIZER tool).
The rules below apply on a general basis, unless limited, as a function of the firmware
version.
Note
A Double Motor Module, a DMC20, a TM54F and a CUA32 each correspond to two DRIVE-
CLiQ participants. This also applies to Double Motor Modules, of which just one drive is
configured.
● A maximum of 14 nodes can be connected to a DRIVE-CLiQ line on the Control Unit.
● Up to 8 nodes can be connected in a row. A row is always seen from the perspective of
● Ring wiring is not permitted.
● Components must not be double-wired.
● The TM54F must not be operated on the same DQ line as Motor Modules.
● The Terminal Modules TM15, TM17 and TM41 have faster sample cycles than the TM31
Figure 1-4
● Only one Line Module (or if connected in parallel, several) can be connected to a Control
● If using Chassis design components, no more than one Smart Line Module and one

and TM54F. For this reason, the two groups of Terminal Modules must be connected in
separate DRIVE-CLiQ lines.
Example: DRIVE-CLiQ line on a CU320 X103
Unit.
Basic Line Module may be jointly operated on one Control Unit (mixed operation on a
DRIVE-CLiQ line).
