Drive Monitoring With Or Without Encoder - Siemens SINAMICS G130 Function Manual

General information about SINAMICS Safety Integrated

3.2 Drive monitoring with or without encoder

3.2 Drive monitoring with or without encoder
If motors without a (safety-capable) encoder are being used, not all Safety Integrated
Functions are available.
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.

SIMOTICS A-1FU (previously: SIEMOSYN).
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 Startdrive tools.
