Safe Stop Reset
The Safe Stop Reset (SS Reset) is a reset from the Safe State or from a stopping
condition to actively monitoring motion. The reset is successful if the SS_In
input is ON and no faults are present.
When an SS Reset is requested, all diagnostic tests that can be performed prior to
outputs being energized are performed prior to a successful SS Reset. If a
diagnostic test can be performed only when outputs are energized, the test is
performed immediately following the SS Reset.
ATTENTION: For all types of reset (automatic, manual, or manual monitored),
if a reset of the Safe Stop or Safe Limited Speed functions can result in machine
operation, the other speed monitoring functions must be configured to detect
and prevent dangerous motion.
ATTENTION: The Safe Stop Reset does not provide safety-related restart
according to EN 60204-1. Restart must be performed by external measures if
automatic restart could result in a hazardous situation. You are responsible for
determining whether automatic restart could pose a hazard.
IMPORTANT An SS Reset is not attempted if the GuardStopInputCycleRequiredStatus
attribute is set (1), indicating that an error, other than an invalid
configuration fault or ESM_In input fault, occurred.
The GuardStopInputCycleRequiredStatus attribute is bit 25 of the [Guard
Status] parameter.
