Safety Integrated with EC-PA-DQ1 + Encoder combination
Introduction
This safety section describes the functional safety information about the EC-PA-DQ1 + GAD/SAD/LAD Single Channel Safety Encoder (SCSE) which is
required to use it in a two encoder safety system in conjunction with a SINUMERIK 840Dsl, software version V4.7 SP2 HF1 or higher (including SINAMICS
drive systems).
Identification
The EC-PA-DQ1 + GAD/SAD/LAD SCSE is the combination of an EC-PA-DQ1 DRIVE-CLiQ adapter and a GAD, SAD or LAD encoder model. For SCSE
applications both elements must have SCSE capability. The items have SCSE capability for the following versions or higher.
Safety capability
The SCSE has the following safety related capabilities according to ISO 13849-1:2008 and IEC61508:2010.
