General information about SINAMICS Safety Integrated
3.2 Drive monitoring with or without encoder
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 use of this safety function without encoder is permitted only for induction motors or synchronous motors of the
1)
SIEMOSYN series.
The configuration of the Safety Integrated functions and the selection of monitoring with or
without encoder is realized in the Safety screens of the STARTER or SCOUT tools.
