N o .
Drive safely referenced (r9721.7 = r9722.23 = 1)
•
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 "Ac-
ceptance test."
2.
It may be necessary to take measures in the higher-level controller to be able to exceed the position limits.
•
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
•
Record the following values: r9708[0], r9713[0], r9720, r9721, r9722
•
Select the time interval and pretrigger so you can recognize when the active SLP
•
limits have been exceeded and the subsequent drive responses
For better analysis, display the following bit values:
r9721.12 (STOP A or B active)
•
r9722.1 (SS1 active; set for STOP B)
•
r9722.7 (internal event; set to 0 when the first safety message occurs)
•
r9722.6 (SLP active)
•
r9722.30 (SLP limit high maintained)
•
r9722.31 (SLP limit low maintained)
•
Select SLP traversing range
Traverse the drive to a safe absolute position within this traversing range
Select SLP
Switch-on the drive and traverse in the negative or positive direction of rotation
Check whether the drive is moving, and after the SLP limit (p9564) has been ex-
•
ceeded that it is braked along the OFF3 ramp before STOP A becomes active
Check whether the following safety messages are pending:
C01715 (10), C30715 (10); SLP1 violated, or
•
C01715 (20), C30715 (20); SLP2 violated
C01701, C30701 (STOP B initiated)
•
C01700, C30700 (STOP A initiated)
•
4. Analyze trace:
As soon as r9708[0] leaves the SLP limits, a safety message becomes active
•
(r9722.7 = 0).
If the upper SLP limit is violated, the safety message "SLP upper limit not main-
•
tained" becomes active (r9722.30 = 0).
If the lower SLP limit is violated, the safety message "SLP lower limit not maintained"
•
becomes active (r9722.31 = 0).
STOP B is initiated as a consequence (with subsequent stop STOP A)
•
5. Save/print the trace and attach to the acceptance report
6. Repeat points 1 to 6 for the other position limit.
