Table 11: Commissioning Test for STO Applications using Safe Stop 1 Time-controlled (SS1-t)
Test procedure
1 Power on the INU.
2 Make sure that the SS1-t function parameters are configured correctly.
3 Check that no safety faults are present.
4 Make sure that the motor runs and stops freely.
5 Request the SS1-t function by de-energizing the inputs assigned to it.
6 Verify that the motor ramps down according to the configured maximum time.
The configured time is also shown in the commissioning report.
7 If a control panel is mounted, check if STO activated is shown on the control panel.
If the control panel is not mounted, check if STO activated is listed in the event log.
8 If STO feedback is used, check the state of the STO feedback to verify that STO is activated. See
9 Energize the inputs that are assigned to the STO function, or deactivate the STO request via fieldbus.
If the fault is configured to direct restart: By deactivating the fault the motor becomes operational and
10
runs within the original speed range.
If automatic acknowledgment is not used: Set an acknowledgment (for example, with an acknowledg-
