● With the CU310-2 Control Unit the connection to the AC/AC Power Modules in
Chassis format is made via the DRIVE-CLiQ connection X100.
● The TM54F must not be operated together on the same DRIVE-CLiQ line as Line Modules
or Motor Modules.
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 U/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.
● For the parallel connection of Active Line Modules of the Chassis-2 format with more than
4 modules, the DRIVE-CLiQ line must be separated. The modules 1 to 3 connected in
parallel must be operated at the 1st DRIVE-CLiQ socket. The remaining modules must be
operated at the 2nd DRIVE-CLiQ socket.
● A maximum of 5 Motor Modules with Safety Extended Functions may be operated on a
DRIVE-CLiQ line. The following condition applies in this regard: T
sampling time) = 125 μs for all axes. In addition to the 5 Motor Modules with Safety Extended
Functions, the following modules may also be operated on a DRIVE-CLiQ line:
– A Line Module if T
– A Motor Module if T
– A maximum of 7 Sensor Modules or DRIVE-CLiQ encoders
Exception: A maximum of 6 Motor Modules with Safety Extended Functions may be
operated on one DRIVE-CLiQ line if the number of connected S120M or S220 modules in
the line is ≥ 3.
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.
