ESR reactions that are not influenced by safety reactions
In order that drive-autonomous ESR reactions in conjunction with Safety Integrated are not
influenced by safety reactions as a result of STOP E, STOP F executed in parallel or
communication failure, then the appropriate delay times must be configured in the drive
regarding safety reactions and the corresponding safety trigger sources to trigger the drive-
autonomous ESR reactions.
Delay times
Delay times in the drive are configured using the following drive parameters:
● p9554 (transition time from STOP E to "Safe Operating Stop" (SOS))
● p9555 (transition time STOP F to STOP B)
● p9580 (wait time after which the pulses are safely cancelled after bus failure)
● p9697 (delay time for the pulse suppression after bus failure)
Safety trigger sources
Using a BICO interconnection of drive parameter p0890 (BI: ESR trigger) ESR reactions can
also be triggered with the safety reactions STOP E, STOP F and communication failure:

Operational performance of the components
The drive components involved in the extended stopping and retraction must be capable of
functioning. If one of these components fails, the full scope of the described reaction no longer
applies. Axis-specific servo or drive alarms indicating the failure of one of these components
are also implicitly signaling that the configured stop or retract reaction of the axis involved is
no longer available or only partially.
