1.4 General functional description
The rotary measuring system is a safe and absolute multi-turn position measuring system with a
safety protocol and a standardized interface that is, however, NOT safety instrumented.
The safety measuring system consists of a
redundant, dual-channel system
in which
●
variant 1: optical and magnetic scanning units, or
●
variant 2: two magnetic scanning units
are arranged on a drive shaft that is designed either as a hollow shaft, a blind-hole shaft, or as a solid
shaft.
The measuring system has primarily been designed for use in systems that require safe position
detection.
The additional safe velocity measurements allow the following safety functions to be implemented
according to DIN EN 61800-5-2:
●
Safe Direction
(SDI)
●
Safe Stop 1
(SS1)
●
Safe Stop 2
(SS2)
●
Safe Operating Stop
(SOS)
●
Safely Limited Velocity
(SLS)
●
Safe Velocity Range
(SSR)
●
Safe Velocity Monitor
(SSM)
●
Safely-Limited Position
(SLP)
●
Safe Cam
(SCA)
As a sensor, the measuring system is always part of a safety chain.
