Function test "Safe Stop 1" (SS1)
This test comprises the following steps:
Table A-8
"Safe Stop 1" function (SS1)
No.
Description
Status
1.
Initial state
•
Drive is "Ready to Run" (P0010 = 0)
•
No safety faults and alarms
•
r9772.0 = r9772.1 = 0 (STO de-selected and inactive)
•
r9772.2 = r9772.3 = 0 (SS1 de-selected and inactive)
2.
Operate the drive
3.
Check that the expected drive operates
4.
Select SS1 while issuing the traversing command
5.
Check the following:
•
Drive speed decreases corresponding to the selected ramp time (if
required, use a stop watch)
•
After the parameterized minimum speed has been fallen below, the drive
coasts-down
•
The drive is braked and held by the mechanical brake if a brake is being
used
•
No safety faults
•
r9772.1 = 1 (STO active)
•
r9772.2 = 1 (SS1 selected)
•
r9772.14 = 1 if safe brake monitoring is enabled
6.
De-select SS1
7.
Check the following:
•
No safety faults
•
r9772.1 = 0 (STO inactive)
•
r9772.2 = 0 (SS1 de-selected)
•
r9772.14 = 0
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 assignment, STO terminals on the control unit
•
Correct parameterization of the SS1 function
