Status
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
STOP B in the event of a limit value vio‐
lation
● If r9714[0] exceeds the active SLS
limit, the motor coasts down to a
standstill (r9722.0 = 1).
● 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).
3. 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.
You have performed the acceptance test of the SLS function.
