SLA : Selection or deselection

SLA: Limit value violation
SLP (limit value violation until a response is initiated)
SCA: Time between violation of a cam start or end po‐
sition and output of the feedback message in
S_ZSW_CAM1
SP with isochronous PROFIsafe telegram

The specified response times are valid for Extended Functions with and without selection.
1)
The specified response times involve internal SINAMICS response times. Program run times in the F‑host and the
2)
propagation time via PROFINET are not taken into account. When calculating the response times between the F-CPU and
the converter, you must take into account that faults in the communication can result in a safety function only being selected
after the PROFIsafe monitoring time (F_WD_Time) has expired. The PROFIsafe monitoring time (F_WD_Time) must also
be included in the calculation when an error occurs.
SLS: Specification of the response time required to initiate a braking response in the drive - or for the output of the "SOS
3)
selected" message to the motion control system.
SSM: The data corresponds to the times between the limit value being undershot up to sending the information via

PROFIsafe.
t_ACT:
5)
For p9511 ≠ 0
t_K is the time for internal communication within the SINAMICS module; t_K can be determined as follows:
6)
t_K = To (for To, see parameter r2064[4])
SP: The data corresponds to the times between acquisition of the safe position and transfer of the safe position via
7)
PROFIsafe.
For the best possible execution (relating to time) on the F‑CPU this component is reduced from 5 · p9500 to 3 · p9500.
8)
In the SINUMERIK ONE Commissioning Tool, the settings for SLA can only be made using the parameter list.
