Introduction
The following descriptions of the safety sub-functions are based on the description according to EN 61800-5-2. For more information on how to implement and parameterize the safety sub-function in the safety option, refer to chapter "Parameterization of the safety sub-functions".
The following table shows the availability of the safety sub-functions described below, depending on the MOVISAFE® CS..A safety option used in each case:
