13.12 System rules, sampling times and DRIVE-CLiQ wiring
Rules and instructions for avoiding overloads
In general any overload must be avoided of a DRIVE-CLiQ line and the components
connected to it through too many components with small sampling times. The following rules
and instruction apply for this:
● A DRIVE-CLiQ line with components with a sampling time of T
connected to components that are permitted for this sampling time. The following
components are permitted:
– Single Motor Modules in booksize format
– Sensor Modules SMC20, SMI20, SMI24, SME20, SME25, SME120 and SME125
– High-frequency damping modules (HF damping modules)
– Additional DRIVE-CLiQ lines must be used for additional components.
● With current controller sampling times 31.25 µs and 62.5 µs, the axes on the DRIVE-CLiQ
connections must be distributed as follows:
– DRIVE-CLiQ socket X100: Infeed, axes 2, 4, 6, ...
– DRIVE-CLiQ socket X101: Axes 1, 3, 5, ...
● For vector V/f control, more than 4 motor modules can only be connected to one DRIVE-
CLiQ line of the Control Unit.
● With a current controller sampling time of 31.25 μs, a filter module should be directly
connected to a DRIVE-CLiQ socket of the Control Unit.
● A maximum of four Motor Modules with Safety Extended Functions may be operated on
one DRIVE-CLiQ line (for current controller sampling time T
further DRIVE-CLiQ components other than a Line Module and Sensor Modules may be
connected to this DRIVE-CLiQ line.
Exception: For SINAMICS S120M, a maximum of 6 S120M with Safety Extended
Functions can be operated on one DRIVE-CLiQ line.
The following applies for the CU Link and the CX32 and NX10/NX15 Control Units:
● In a topology with CU Link, the SINUMERIK NCU is DRIVE-CLiQ master for the NX and
the SIMOTION D4xx is master for the CX32.
● The CX32 or NX10/NX15 Control Units are master for the subordinate components.
● The connection to the Control Unit is obtained from the PROFIBUS address of the CX/NX
(10 → X100, 11 → X101, 12 → X102, 13 → X103, 14 → X104, 15 → X105).
● It is not permitted to combine SIMOTION Master Control Units and SINUMERIK Slave
Control Units.
● It is not permitted to combine SINUMERIK Master Control Units and SIMOTION Slave
Control Units.
