Today I found V3 coil on ETMY IM stage is not working.
I set DC offset (10000 cnts) in K1:VIS-ETMY_IM_V3_OFFSET but TM PIT oplev value is not changed even though V3 coil output value is changed. When you do the same thing with V1, the oplev signal moves about 3 urad. I wanted to see the output from the coil driver, but unfortunately I couldn't because the output didn't connect digital system.
So, I and Miyo-san go to Y-end to connect the output to the digital system and investigate more.
