Siemens SINUMERIK 828D Commissioning Manual page 155

In addition to the binding wiring rules that must be observed, some additional recommendations
as well as topology examples for DRIVE-CLiQ wiring are provided in the PPU manual.
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, the SIZER tool should be used to check the topology.
Note
Every topology that SIZER permits can also run and is therefore correct (SINAMICS S120 D
Function Manual /FH1/).
DRIVE-CLiQ rules
The wiring rules below apply to standard cycle times (servo 125 µs). For cycle times that are
shorter than the corresponding standard cycle times, additional restrictions apply due to the
computing power of the Control Unit.
The rules below apply on a general basis, unless limited, as a function of the firmware version.
● A maximum of eight DRIVE-CLiQ nodes can be connected in one row. A row is always
seen from the perspective of the Control Unit.
This number reduces to a maximum of four DRIVE-CLiQ nodes in one row when the
extended functions of drive-based Safety Integrated are configured.
● A maximum of 14 nodes can be connected to one DRIVE-CLiQ line on a Control Unit.
● Ring wiring is not permitted.
● Components must not be double-wired.
