} Braking ramp in normal operation
The drive starts with the configured braking ramp when safety function SS1 has been
activated. Once the time has elapsed, STO is activated.
} E­STOP braking ramp:
The drive starts with the configured braking ramp when
– there is an internal error
– limit values are exceeded
} Safety function STO is activated when
– the actual braking period is longer than the configured STO delay time.
– the configured limit value for the position error is exceeded.
– another error occurs while SS1 is activated
– the STO delay time has elapsed
} Automatic STO at standstill
A standstill threshold for activating the safety function STO can be specified in the Con­
figurator.
Safety function STO is activated when
– standstill is achieved while the STO delay time is running.
– the STO delay time has elapsed.
