Product description
AX5805 13
3.3.1 Reaction times for the AX51xx
The reaction time is the amount of time from a safety-related event is received (as an input signal to the
AX5805) until the internal circuits are switched off. If the TwinSAFE communication is to be included in the
calculation, the watchdog time of the TwinSAFE connection must be added to this. For a worst-case
consideration, the maximum time with update of the CoE data must always be used.

STO mode.
