Interconnecting DRIVE-CLiQ components

For Safety Integrated Functions, the general DRIVE-CLiQ rules apply as a basic principle. You
will find these rules in Chapter "Rules for connection with DRIVE-CLiQ" in the following Manual:
● "SINAMICS S120 Drive Functions" Function Manual
cs/ww/en/view/109771805)
Beyond this, the following rules also apply to Safety Integrated:
Rules for Safety Integrated Basic Functions
● Maximum of 4 drives per DRIVE-CLiQ line for control via PROFIsafe
Rules for Safety Integrated Extended Functions
● Maximum of 6 servo axes for default clock cycle settings (safety monitoring clock
cycle = 12 ms; current controller cycle = 125 μs); of which a maximum of 4 servo axes are
in one DRIVE-CLiQ line
● Maximum of 6 vector axes for the following clock cycle settings (safety monitoring
cycle = 12 ms; current controller cycle = 500 μs)
● One Double Motor Module corresponds to 2 DRIVE-CLiQ participants.
● On Double Motor Modules, on the drive objects, different values for p9511 are not permitted,
even if the values in p0115[0] are different.
● A maximum of 4 Motor Modules with Safety Integrated Extended Functions may be
operated on one DRIVE-CLiQ line (for current controller cycle T
further DRIVE-CLiQ components other than a Line Module and Sensor Modules may be
operated on this DRIVE-CLiQ line.

Drive monitoring with or without encoder

In the Safety Integrated system, encoderless safety operation is only supported for spindles
with induction motors.
If motors without a (safety-capable) encoder are being used, not all Safety Integrated Functions
can be used.
Note
Definition: "Without encoder"
When "without encoder" is used in this manual, then this always means that either no encoder
or no safety-capable encoder is being used.
In operation without encoder the actual speed values are calculated from the measured
electrical actual values. Therefore, speed monitoring is also possible during operation without
encoder.
The configuration of the Safety Integrated Functions and the selection of monitoring with or
without encoder is realized in the SINUMERIK ONE Commissioning Tool.
