System sampling times and number of controllable drives
This chapter contains a list of the axes that can be operated with SINAMICS S120
depending on the cycle times in the various control modes. The other available remaining
computation times are available for options (e.g. DCC).
Cycle times for the "servo" control mode
The following table shows the number of axes that can be operated depending on the
selected cycle times in the "servo" control mode:

1) Valid for TM31 or TM15IO; for TM54F, TM41, TM15, TM17, TM120 - restrictions are possible dependent on the set
sampling time.
2) In the clock cycle level 31.25 µs you can additionally set-up the following objects:
- 1 servo axis with a sampling time of 125 µs
- 2 U/f axes with a sampling time of 500 µs
The following combinations are permissible for current controller cycle mixed operation:
● Servo with 125 µs and servo with 250 µs (only 2 clock cycle levels may be mixed)
● Servo with 62.5 µs and servo with 125 µs (only 2 clock cycle levels may be mixed)
Note the following: 1 axis with 31.25 µs corresponds to
● 2 servo axes with 62.5 µs
● 4 servo axes with 125 µs
● 8 U/f axes with 500 µs
