Figure A-8 Diagram 2 - acceptance test SLS with stop reaction STOP B
Procedure
To perform the acceptance test of the SLS function, proceed as follows:
Status
If you are using multiple SLS levels, repeat the test for each of the SLS levels.
1. The inverter is ready
Check the following:
● The inverter signals neither faults nor alarms of the safety functions (r0945[0…7],
r2122[0…7]).
● SLS is not active (r9722.4 = 0).
Go online with the STARTER and configure the following trace:
● Trigger on variable - bit pattern (r9722.7 = 0)
● Record the following values: r9714[0], r9714[1], r9722
Display the bits r9722.0/.4/.7/.9/.10
● Select the interval and pretrigger so you can recognize when the active SLS limit has
been exceeded and the subsequent drive responses.
