484 Verification and validation
OR
b) with time monitoring:
- SDI.10 SDI activation monitoring method = Time
- drive parameter 23.13 deceleration time 1 (or 23.15 deceleration time 2)
-SDI.12 SDI delay.
Indication:
• SDI.23 SDI positive output A
• SDI.24 SDI positive output B
• SDI.33 SDI negative output A
• SDI.34 SDI negative output B.
Test the SDI function as used in the application. Pay attention to testing of the
relevant fault situations for the application, for example a fault in the drive, safety
encoder fault, etc.
Check that the correct monitoring direction and limiting degree is configured
according to the application.
Start the drive and make sure that you can run the motor in both directions if possible.
If the positive direction is your allowed direction, test the SDI function to the positive
direction as described below. Otherwise do the validation test to the other direction by
replacing all directions below to opposite values in the procedure.
1. Run motor to the positive direction.
2. Activate SDI function to positive direction.
3. Make sure that the SDI positive indication (SDI.23) activates.
4. Stop the motor, or give 0 rpm user reference, and make sure that the motor shaft
is stopped correctly and it is not crawling too much to the forbidden direction, and
the SDI is not tripped to tolerance limit.
5. Restart the drive to the positive user reference.
6. Remove the positive SDI request.
7. Acknowledge SDI function if manual acknowledgement is used.
8. Activate the negative SDI request.
9. Make sure that the motor decelerates as required and no tripping fault occurs
during the deceleration.
10. Make sure that the SDI negative indication (SDI.33) activates when the motor
speed reaches zero rpm, or when the motor rotates to the allowed direction.
