Abstract:

I offloaded REFL WFS PZTs by using PICO motors.
All PZTs signals except for DC1_P (REFL WFS3) can be offloaded but DC1_P PZT doesn't seem to work well.

Detail:

I offloaded REFL WFS PZTs by using PICO motors.
After offload, PZT feedback signals became around aero except for DC1_P PZT (fig1).
Figure 2 shows the time series data of DOF1_P signals.
Though PZT signals increased very rapidly, error signals doesn't seem responded.
So, WFS F3 pitch PZT seems to have a problem.

Figure 3 and 4 shows the PICO medm screen after my work.
Note that REFL_WFS{1,2} YAW pico motor position was refleshed (changed from 0 to 700/300) when turning on the PICO script.
So, these values are changed in SDFs though I didn't move PICO motors for REFL_WFS{1,2}_YAW.
