5 General function description
General function description
The encoder (SR) is a safe and absolute multi-turn position measuring system with a standardised,
non-safety-related interface and a safety protocol.
The encoder (SR) consists of a redundant two-channel system in which two magnetic scanning units
are arranged on a drive shaft (blind or solid shaft version).
The additional safe speed detection allows the following safety functions to be implemented at system
level in accordance with IEC 61800-5-2 (→ Programming manual):
Sichere Bewegungsrichtung Safe direction (SDI)
Sicherer Stopp 1 Safe stop 1 (SS1)
Sicherer Stopp 2 Safe stop 2 (SS2)
Sicherer Betriebshalt Safe operating stop (SOS)
Sicher begrenzte Geschwindigkeit Safely limited speed (SLS)
Sicherer Geschwindigkeitsbereich Safe speed range (SSR)
Sichere Geschwindigkeitsüberwachung Safe speed monitor (SSM)
Sicher begrenzte Position Safely-limited position (SLP)
Sicherer Nocken Safe cam (SCA)
As a sensor, the encoder (SR) is always part of a safety chain.
WARNING
Failure of the safety sub-function
w Handheld radio equipment operated within a radius of <200 mm of the encoder (SR) can
interfere with the safety sub-functions.
u Do not operate handheld radio equipment at a distance of <200 mm from the encoder
(SR).
The safety sub-functions of the encoder (SR) are established by
• making each of the two scanning channels largely fail-safe through its own diagnostic measures.
• the encoder (SR) internally carrying out a two-channel comparison of the positions recorded by the
two channels, also determining the speed on two channels and transferring the safe data to the
controller in the CANopen safety protocol via a safety-related data object (SRDO) with
corresponding safety mechanisms.
• the encoder (SR) switching the device to a safe state in the event of a failed channel comparison or
other errors detected by internal diagnostic mechanisms.
• by securing the encoder (SR) initialisation and the execution of the preset adjustment function
accordingly.
• the downstream safety-related evaluation unit (e.g. safe PLC) additionally checking whether the
speed and position data received are within the position window expected by the controller.
Unexpected position data include position jumps, tracking error deviations and incorrect direction of
travel.
• the controller initiating appropriate safety measures (to be defined by the system manufacturer)
when errors are detected.
• the system manufacturer carrying out a secured test during set-up and each time a parameter is
changed.
The safety sub-functions are described in detail in the programming manual.
