Siemens SINAMICS Series Function Manual

General information about SINAMICS Safety Integrated
3.2 Drive monitoring with or without encoder
Safety Integrated
30 Function Manual, 07/2016, A5E03264275A
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.

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.
