Description of Safety Integrated functions
4.2 Safety Integrated Extended Functions
Filter time
If the determination of the acceleration leads to very noisy signals, the drive cannot
reasonably monitor the acceleration.
Remedy
● In this case, increase the "SLA filter time" (p9576).
Note that SLA reacts with a delay when you increase the filter time.
Stop response
If the SLA subsequently detects violation of the acceleration limit, the drive initiates the stop
response configured using p9579.
Principle of operation
The following diagram shows the principle of operation of SLA:
