● The drive is braked by external setpoint value specification.
● The SLS limit value (level 1 = p9531[0]) is monitored once the SLS delay time (p9551) has
elapsed.
● If the SLS limit value (level 1) is violated, the drive executes the set stop response
(level 1 = p9563[0]).
● The drive signals the "SLS active (level 1)" status in the status bit of the PROFIsafe telegram.
● You can utilize this status in the higher-level controller.
● Switchover to SLS (level 2) is performed via the control bit of the selected PROFIsafe telegram.
● The drive is braked by external setpoint value specification.
● Monitoring of the SLS limit value (level 2 = p9531[1]) becomes effective once the delay time for
SLS switchover = SLS delay time (p9551) has elapsed.
● If the SLS limit value (level 2) is violated, the drive executes the set stop response
(level 2 = p9563[1]).
● The SLS active (level 1 and level 2) statuses are signaled in the status bits of the PROFIsafe
telegram.
● You can utilize these values in the higher-level controller.
● The drive ends monitoring of the SLS limit value with deselection of SLS (level 2) via the control
bit of the selected PROFIsafe telegram.
● The drive may be operated freely.
