After discussing with Jeff this morning, I have flipped the sign of the Coil Output filters Gain to get the damping loops going on both RM1 and RM2. These changes have been accepted in the SDF. Jeff had set it to nominal value (i.e how it was pre-vent), however this makes the suspension very angry with the WD tripping immediately.
RM1 Coil Output Filter Gain:- H1:SUS-RM1_M1_COILOUTF_UL_GAIN -1 H1:SUS-RM1_M1_COILOUTF_LL_GAIN 1 H1:SUS-RM1_M1_COILOUTF_UR_GAIN 1 H1:SUS-RM1_M1_COILOUTF_LR_GAIN -1
RM2 Coil Output Filter Gain:-
H1:SUS-RM2_M1_COILOUTF_UL_GAIN 1 H1:SUS-RM2_M1_COILOUTF_LL_GAIN -1 H1:SUS-RM2_M1_COILOUTF_UR_GAIN -1 H1:SUS-RM2_M1_COILOUTF_LR_GAIN 1
This sign change is done to compensate for the sign change of the osem voltages (now inmons are +ve counts, pre-vent it was -ve counts), along with wrong polarity of the magnets (which has always been there in RM2).
Both RM1 and RM2 are damping fine now.
I also took Un-damped and Damped osem spectra (un-calibrated) for both RM1 and RM2 and the results shows that the BOSEM sensor noise above 10Hz (since ISI is locked) is acceptable, even though slightly high due to declining health (their OLC are on a gradual decline) of the BOSEMs itself.
