Acceptance tests for Safely Limited Speed with encoder (Extended Functions)
SLS with encoder with s top response "STOP A"
N o .
N o te:
The acceptance test must be carried out separately for each configured control and each SLS speed limit used.
Control can be realized without selection 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)
•
SLS inactive (r9722.4 = 0)
•
Note: SLS is active for motion monitoring without selection.
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 active speed limit.
•
Note that the internal limits (r9733[0], r9733[1] and r9733[2]) are removed by selecting "Start acceptance test".
•
3. Configure and activate trace recording
Trigger: Trigger on variable - bit pattern (r9722.7 = 0)
•
Record the following values: r9714[0], r9721, r9722
•
Select the time interval and pretrigger so you can recognize when the active SLS limit
•
has been exceeded and the subsequent drive responses
For better analysis, display the following bit values:
r9721.12 (STOP A or B active)
•
r9722.0 (STO active; set for STOP A)
•
r9722.4 (SLS active) and r9722.9/.10 (active SLS level)
•
r9722.7 (internal event; set when the first safety message occurs)
•
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 coasting down or a configured holding brake is closed
Check whether the following safety messages are pending:
C01714 (x00), C30714 (x00); x = 1...4 depending on the SLS level (safely limited
•
speed exceeded)
C01700, C30700 (STOP A initiated)
