Today, like yesterday, we used AS A 45Q YAW to damp the roll modes. The ITMY settings were different today compared to yesterday; the sign and the phase has changed. Currently the roll mode damping is working with settings
Optic | ETMY | ETMX | ITMY | ITMX |
Roll mode frequecy [Hz] | 13.816 | 13.889 | 13.93 | 13.978 |
Phase [deg] | 0 | -90 | 0 | -60 |
Filters on | FM 3,4 | FM 2,3,4,7 | FM 3,4 | FM 2,3,4 |
Gain | -50 | 10 | 100 | 100 |
The filter settings are in the guardian, however the H1:ASC-OUTMATRIX element; H1:ASC-OUTMATRIX_TESTMASS_DAMP_1_3, does not get set from 0 to 1 in the guardian, so these filters do not currently turn on automatically.
