17 Appendix: Response time
The following tables specifies the max. guaranteed response time, which is
necessary from activation of a safety input to deactivation of a safety output.
The specified response times are valid, if the connection (FSoE connection
to encoder box or PROFISafe connection to superior safety control) is oper-
ated with the specified watchdog and the safety application logic has no fur-
ther delays. Otherwise the response time is higher. For further information
contact KEBA. For error reaction times of slave module please contact the
corresponding manufacturers.
