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
● With current controller sampling times 31.25 µs and 62.5 µs the axes to the DRIVE-CLiQ
● For a current controller cycle of 31.25 μs, a filter module should be directly connected to a
● A maximum of four Motor Modules with Safety Extended Functions (dbSI-1/2) may be

DRIVE-CLiQ line must be divisible by one another with an integer result, or all the
sampling times set for the components must be an integer multiple of a common "base
cycle".
– Example 1: A Line Module with 250 µs and Motor Modules with 125 µs can be
operated together on a DRIVE-CLiQ line ("base cycle": 125 µs)
– Example 2: A Line Module with 250 µs and a Motor Module with 375 µs can be
operated together on a DRIVE-CLiQ line ("base cycle": 125 µs)
If the current controller sampling time T
sampling time that does not match the other drive objects in the DRIVE-CLiQ line, the
following solutions are available:
– Insert the modified drive object into a separate DRIVE-CLiQ line. Note here that a total
of 2 cycle levels are permissible on a Control Unit.
– Modify the current controller sampling times and/or the sampling times of the
inputs/outputs of the other drive objects similarly so they match the modified sampling
time again.

connected with 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.
connections must be distributed as follows:
– DRIVE-CLiQ socket X100: Infeed, axes 2, 4, 6, ...
