Incremental Encoder FG 41
The measuring system has been designed so that it can be used in systems which require the
following safety functions according to EN 61800-5-2:
·
Safe Direction
(SDI)
·
Safe Stop 1
(SS1)
·
Safe Stop 2
(SS2)
·
Safe Operating Stop
(SOS)
·
Safely Limited Speed
(SLS)
·
Safe Speed Range
(SSR)
·
Safe Speed Monitor
(SSM)
·
Safely-Limited Acceleration (SLA)
·
Safe Acceleration Range (SAR)
·
Safely-Limited Position
(SLP)
·
Safely-Limited Increment (SLI)
·
Safe Cam
(SCA)
The measuring system as a sensor is always part of a safety chain.
The following shaft designs can be used for the mechanical coupling:
·
Solid shaft
Depending on the safety functions safety-related differences arise:
·
SIL3/PLe/Kat.3,
in conjunction with velocity oriented safety functions
·
SIL2/PLd/Kat.3,
in conjunction with positioning oriented safety functions
