Status
3. Select SS1
3.1. Select SS1 while the motor is switched on.
Test each configured activation, e.g. via digital inputs and PROFIsafe.
3.2. Check: The inverter signals neither faults nor alarms of the safety func‐
tions (r0945[0…7], r2122[0…7]).
3.3. Analyze the trace.
● SS1 is active after selecting SS1 (r9722.1 = 1).
● The motor brakes on the OFF3 ramp.
● STO becomes active if the velocity drops below the shutdown velocity
p9560 (r9722.0 = 1).
● The recorded curves of r9714[0] and r9714[1] are approximately
parallel.
4. Deselect SS1
4.1. Deselect SS1.
4.2. Check the following:
● SS1 is not active (r9722.1 = 0).
● The inverter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
You have completed the acceptance test of the SS1 function.
