Acceptance tests for Safely Limited Speed without encoder (Extended Functions)
SLS without encoder with stop 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 without encoder (p9506 = 1 or p9506 = 3)
•
For "Motion monitoring without selection (Page 205)":
•
- "Safety without selection" configured (p9601 = 24hex or 25hex)
- "Safety without selection" activated (p9512.4 =1)
No safety faults and alarms (r0945[0...7], r2122[0...7], r9747[0...7]) at the drive or
•
TM54F (if one is being used); see note "Non-critical alarms" at the beginning of Sec-
tion "Acceptance tests".
2.
It may be necessary to take measures in the higher-level controller to be able to exceed the active speed limit.
•
Note that regarding SDI, the internal limits (r9733[0], r9733[1] and r9733[2]) are removed by selecting "Start
•
acceptance test".
After selecting SLS, the drive must be switched on within 5 seconds.
•
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
Select SLS with level x
Switch on the drive and specify the setpoint above the SLS limit
Check whether the drive is moving, and after the SLS limit (p9331[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)
•
4. Analyze trace:
If r9714[0] exceeds the active SLS limit, a Safety message (r9722.7 = 0) becomes
•
active
STOP A is initiated as a consequence
•
For better analysis, display the following bit values:
