F2_GAS is saturated
Output value on TOWER_OVERVIEW and DAC_MONITOR show around 26000 and 24700, respectively.
But DAC0_5 on k1iy1 is saturated (See Fig1).

I simulated upsampling process from 2kHz user model to 64kHz IOP model.
DAC output is surely saturated when the user model outputs around 26000 counts.
Fig2 shows the signal on the IOP model when user model outputs constant 26000 counts.
Maximum value reaches 33000 counts.

In my estimation, when the 2kHz user model outputs 25847 counts, the signal is saturated on the IOP model.

temperature is stable.

F1 & F3 were also changed, but they are about 0 now.
