Same problem as 19295.
Some positive amount of actuation gives negative displacement in F2, F3, and BF GAS filters.
But, there's no way to tell if it's the LVDTs that are negated or the coils themselves.
For now, I will change the direction of the coils.
F2_COILOUTF_GAS_GAIN: 1 -> -1
F3_COILOUTF_GAS_GAIN: 1 -> -1
BF_COILOUTF_GAS_GAIN: 1 -> -1
Hi Terrence,
How about checking the BFV signals at the same time?
If the coils have opposite sign, BFV signals should move negative direction.
On the other hand,if the GAS LVDTs have opposite signs, BFV signals should move positive direction.
I compared F0-F3 signal with BF V and indeed now they're all aligned. So it's all good unless BF V is also inverted.
I can't compare BF GAS though but I guess this isn't a big issue.
