A.3 Acceptance tests (recommendations)
N o .
Select SLS with level x
Note: SLS is already active for motion monitoring without selection.
Switch on the drive and specify the setpoint above the SLS limit
Check whether the drive is moving, and after the SLS limit (p9531[x]) has been ex-
•
ceeded that it is braked to a standstill along the OFF3 ramp
Check whether the following safety messages are pending:
C01714 (x00), C30714 (x00); x = 1...4 depending on the SLS level (safely limited
•
speed exceeded)
C01708, C30708 (STOP C initiated)
•
4. Analyze trace:
If r9714[0] exceeds the active SLS limit, a safety message (r9722.7 = 0) becomes
•
active
STOP C is initiated as a consequence
•
For better analysis, display the following bit values:
r9721.13 (STOP C active)
•
r9722.2 (SS2 active; set for STOP C)
•
r9722.3 (SOS active)
•
r9722.4 (SLS active) and r9722.9/.10 (active SLS level)
•
r9722.7 (internal event; set when the first safety message occurs)
•
5. Save/print the trace and add it to the acceptance report (refer to the example below)
6. Deselect SLS or bring the speed setpoint back to the required range
Please note that after safe acknowledgment of the safety messages, the actual set-
•
point becomes effective again.
Acknowledging safety messages
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)
