472 Verification and validation
OR
b) With time monitoring:
- SSE.14 SSE monitoring method = Time
- SSE.15 SSE delay for STO.
Indication:
• SSE.21 SSE output
• SSE.21 SSE completed output
• FSOGEN.11 Stop completed output.
3. If you made any changes, download and validate the configuration with the Drive
composer pro PC tool.
4. Make sure that you can run and stop the motor freely. Start the drive and
accelerate the motor to the maximum speed of the application.
5. Activate the SSE function. For example, press the emergency stop button which
is wired to FSO module input for the SSE function.
6. Remove the SSE function user request.
7. a) If manual acknowledgement (or safebus acknowledgement) is in use
: Verify by
trying to acknowledge the function, that it is not possible before the motor speed
is low enough:
• With safe speed estimation: FSOGEN.51 Zero speed without encoder.
• With safety encoder: FSOGEN.52 Zero speed with encoder.
b) If automatic acknowledgement is in use
: Verify that the function is not
acknowledged before the motor is in safe state, see the conditions above.
8. Make sure that the motor speed decelerates as expected and the FSO does not
trip to the monitoring limit (ramp or time).
9. Start the drive and accelerate the motor to the maximum speed of the application.
10. Activate the SSE function. For example, press the emergency stop button which
is wired to the FSO module input for the SSE function.
11. Remove the SSE function user request.
12. Activate the coast stop of the drive.
You can, for example, cause an external fault trip in the drive. For more
information, see the drive firmware manual (Group 31 Fault functions).
13. Make sure that the FSO trips the drive, and activates the STO function according
to the application requirements.
14. Make sure that the acknowledgement of the STO function is not possible before
the motor is in safe state
