Delay time when selecting SLS -> SLS active
p9551
Sets the delay time for SLS switchover.
This delay time is active in the following cases:
● Selecting SLS:
Monitoring only becomes active after the configurable delay time has
elapsed. Within this time, the actual velocity must be below the (selected)
limit.
● This delay time is also incurred when activating SLS from the "SOS and
SLS in active" state.
● Reducing the 1st limit value via PROFIsafe - or switching over to a lower
maximum velocity level:
The actual velocity of the drive must have dropped below the new limit
within the delay time. The existing limit remains active during the delay
time. The lower limit value becomes active after the delay time has ex‐
pired.
The delay time is not active in the following cases:
● Deselecting SLS
● Switching over to a higher limit value:
The higher limit value immediately becomes active.
In operation, the parameterized delay time cannot be changed. If you require
various delay times in your application, then you must realize this using a
time-delayed transfer of the SLS limit value using the F-PLC.
Maximum velocity (V_max) level 1
p9531[0]
Up to 4 parameterizable SLS velocity limit values must be specified based on
the results of the risk analysis. Also when SLS is activated, these limit values
can be toggled between.
Depending on the particular situation, the "Delay time, select SLS -> SLS
active" acts for switchover (see above).
Switchover between these 4 values
The value of a selected maximum speed stage 1 is transferred via PROFI‐
safe if the "SLS limit via PROFIsafe for SLS level 1" checkbox is activated.
