Introduction

The following descriptions of the safety subfunctions are based on the description according to EN 61800-5-2. For more information on how to implement and parameterize the safety subfunction in the safety option, refer to chapter "Parameterization of the safety subfunctions".

The following table shows the availability of the safety subfunctions described below, depending on the MOVISAFE® CS..A safety option used in each case:
