Safe stop 2 monitoring
The Safe stop 2 monitoring function (SS2-M) monitors
} Whether the set delay time has expired (to controlled braking of the motor) or the value
for standstill detection for automatic SOS is below the limit value
and
} Whether the standstill position ultimately remains within a configured tolerance window.
Reaction:
} If the monitoring function SS2-M is triggered, the "Braking ramp" output switches off.
The drive controller's braking ramp is activated.
