Acceptance test for Safe Stop 2 (SS2)
N o.
N o te:
The acceptance test must be individually performed for each configured control.
Control can be realized via TM54F, onboard terminals (CU310-2) or via PROFIsafe.
1. Initial state
Drive in the "Ready" state (p0010 = 0)
•
Safety Integrated Extended Functions enabled (p9601.2 = 1)
•
Safety functions enabled (p9501.0 = 1)
•
Safety configured with encoder (p9506 = 0 or p9506 = 2)
•
SS2 deselected (r9720.2 = 1)
•
SS2 inactive (r9722.2 = 0)
•
SOS inactive (r9722.3 = 0)
•
No Safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7]) at the drive and TM54F
•
(if used); see note "Non-critical alarms" at the beginning of Section "Acceptance test."
2. Run the drive
Check whether the correct drive is operational
•
3. Configure and activate trace recording.
Trigger: Trigger on variable - bit pattern (r9720.2 = 0)
•
Record the following values: r9714[0], r9720, r9722
•
Select the time interval and pretrigger so you can recognize the selection of SS2 and the
•
transition into the subsequent SOS state
For better analysis, display the following bit values:
r9720.2 (deselection SS2)
•
r9722.2 (SS2 active)
•
r9722.3 (SOS active)
•
Select SS2 while the drive is moving
Drive brakes along the OFF3 ramp (not in the case of SS2 with external stop (SS2E))
•
Subsequent SOS state is activated
•
No safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7]) at the drive and TM54F
•
(if one is being used)
4. Analyze trace:
SOS is triggered after the SS2 timer (p9352/9552) has expired.
•
5. Save/print the trace and add it to the acceptance report (refer to the example below)
6. Deselect SS2
Check whether the drive is operating with the setpoint again
•
No safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7]) at the drive and TM54F
•
(if one is being used)
