The inverter is ready
The inverter signals neither faults nor alarms of the safety functions
•
(r0945[0...7], r2122[0...7]).
SS1 is not active (r9722.1 = 0).
•
Go online with the STARTER and configure the following trace:
Trigger on variable - bit pattern (r9720.1 = 0)
•
Record the following values: r9714[0], r9714[1], r9722
•
Display the bits r9722.0/.1
Select the time interval and pretrigger so you can recognize the selection
•
of SS1 and the transition into the subsequent STO state.
Start the trace.
•
Switch on motor
2.1. Enter a speed setpoint ≠ 0.
2.2. Switch on the motor (ON command).
2.3. Check that the correct motor is running.
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
functions (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.
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]).
