Function test "Safely-Limited Speed" (SLS)
This test comprises the following steps:
Table A-9
"Safely-Limited Speed" function (SLS)
No.
Description
Status
1.
Initial state
•
Drive is "Ready to Run" (P0010 = 0)
•
No safety faults and alarms
•
r9772.4 = r9772.5 = 0 (SLS de-selected and inactive)
2.
Operate the drive (if the machine permits it, at a higher speed than the
parameterized safely-limited speed)
3.
Check that the expected drive operates
4.
Select SLS while issuing the traversing command
5.
Check the following:
•
r9772.4 = 1 (SLS selected)
•
Drive speed decreases corresponding to the selected ramp time or SLS
mode (if required, use an oscilloscope)
•
After the parameterized safely-limited speed has been fallen below, the
speed remains below this limit
– In SLS mode 1 à correct, must be no fault
– In SLS mode 0 à LSTO (safety fault at ramping end)
– In SLS mode 2 à LSTO (immediately)
•
r9772.5 = 1 (SLS active)
6.
De-select SLS
7.
Check the following:
•
No safety faults
•
r9772.4 = r9772.5 = 0 (SLS de-selected and inactive)
8.
Check that the expected drive operates if so the following is tested:
•
The wiring between the control unit and power module is correct
•
Correct assignment, drive No. – inverter power module – motor
•
Correct functioning of the hardware
•
Correct wiring of the shutdown paths
•
Correct parameterization of the SLS function
