Transferring the first limit value via PROFIsafe
SINAMICS offers the option of influencing the first SLS limit value via PROFIsafe:
● The transfer of the first SLS limit value via PROFIsafe is active if the speed level 1 in the
PROFIsafe telegram is selected and the bit "Enable transfer SLS (SG) limit via
PROFIsafe" (p9501.24) is set.
● S_SLS_LIMIT_A has the value range 1 ... 32767; the following applies:
– 32767 ≙ 100 % of the 1st SLS level
– The actually monitored limit value is calculated as follows:
● Also in this case, speed levels 2, 3 and 4 can be parameterized and selected.
● In operation, the selected 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 your control system (F-CPU).
● If an incorrect SLS limit value is transferred, then the converter responds with the stop
response of speed level 1 parameterized in p9563 and the safety message
C01711(1041).

SLS limit value = (S_SLS_LIMIT_A/32767) × p9531[0]
