3.
You have performed the acceptance test of the SLS function.

2.5. Check that the correct motor is running.
The following tests depend on how you have set the SLS function during
commissioning:
First diagram:
The inverter responds with STOP A in
the event of a limit violation.
2.6. The inverter signals the following:
C01714 and C30714 (safe velocity
•
limit exceeded)
C01700 and C30700 (STOP A
•
initiated)
2.7. Analyze the trace.
After SLS is selected, the inverter signals "SLS is active" (r9722.4 = 1).
•
The inverter signals the selected SLS level (r9722.9 and r9722.10).
•
If r9714[0] exceeds the active SLS limit, the inverter signals an internal event
•
(r9722.7 = 0).
STOP A in the event of a limit value
violation
If r9714[0] exceeds the active SLS
•
limit, the motor coasts down to a
standstill (r9722.0 = 1).
Deselect SLS
3.1. Deselect SLS.
3.2. Check: SLS is not active (r9722.4 = 0).
3.3. Acknowledge the messages for the safety functions.
A.1 Examples of acceptance tests
Second diagram:
The inverter responds with STOP B in
the event of a limit violation.
The inverter signals the following:
C01714 and C30714 (safe velocity
•
limit exceeded)
C01701 and C30701 (STOP B
•
initiated)
C01700 and C30700 (STOP A
•
initiated)
STOP B in the event of a limit value
violation
If r9714[0] exceeds the active SLS
•
limit, the motor brakes on the OFF3
ramp (r9722.1 = 1).
After braking, STO is active
•
(r9722.0 = 1).
