10.5.2.5 Acceptance test for Safe Operating Stop (SOS)
Table 10- 15 "Safe Operating Stop" function
No. Description Status
Note:
The acceptance test must be individually conducted for each configured control.
The control can be realized via TM54F or via PROFIsafe.
Initial state
• Drive in "Ready" state (p0010 = 0)
• Safety Integrated Extended Functions enabled (p9601.2 = 1)
• Safety functions enabled (p9501.0 = 1)
• 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".
2. It may be necessary to take measures in the higher-level control to be able to run the drive with activated SOS.
Configure and activate trace recording.
• Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
• Record the following values: r9713[0], r9720, r9721, r9722
• Select the time interval and pretrigger so you can recognize start-up of the drive and
infringement of the SOS tolerance window (p9330/p9530)
For better analysis, display the following bit values:
• r9720.3 (deselect SOS)
• r9721.12 (STOP A or B active)
• r9722.0 (STO active; set for STOP A)
• r9722.1 (SS1 active; set for STOP B)
• r9722.3 (SOS active)
• r9722.7 (internal event; set on the occurrence of the first Safety message)
Select SOS
Run the drive beyond the standstill limit set in p9330/p9530
• Check that the drive moves briefly and then decelerates back to a standstill
Check whether the following Safety messages are pending:
• C01707, C30707 (Tolerance for safe operating stop exceeded)
• C01701, C30701 (STOP B initiated)
3.
• C01700, C30700 (STOP A initiated)
Analyze trace:
• As soon as r9713[0] (unit µm or m°) leaves the tolerance window, a Safety message
(r9722.7 = 0) becomes active
4.
• As a consequence, the drive is brought to a standstill with STOP B and STOP A
5. Save/print the trace and add it to the acceptance report (refer to the example below)
Deselect SOS and acknowledge Safety messages 6.
• No Safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7])
