Table 10- 14 "Safe Stop 2" function
No. Description Status
Note:
The acceptance test must be individually performed for each configured control.
Control may be via TM54F or PROFIsafe.
Initial state
• Drive in "Ready" state (p0010 = 0)
• Safety Integrated Extended Functions enabled (p9601.2 = 1)
• Safety functions enabled (p9501.0 = 1)
• SS2 selected (r9720.2 = 0)
• SS2 inactive (r9722.2 = 0)
• SOS inactive (r9722.3 = 0)
1.
• No Safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7]); see note "non-
critical alarms" in section "Acceptance tests".
Run the drive 2.
• Ensure that the correct drive is running
Configure and activate trace recording.
• Trigger: Trigger on variable - bit pattern (r9720.2 = 0)
• Record the following values: r9714[0], r9714[1], 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
• The drive decelerates along the OFF3 ramp
• Subsequent SOS state is activated
3.
• No Safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7])
Analyze trace:
• SOS is triggered after the SS2 timer (p9352/9552) has expired.
4.
• r9714[0] is displayed in the unit [µm/Safety clock cycle or m°/Safety clock cycle]
5. Save/print the trace and add it to the acceptance report (refer to the example below)
Deselect SS2
• Ensure that the drive is running with the setpoint again
6.
• No Safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7])
