What does these frequent dropsACC1 Amplitude means?
I’m going to guess, but looking at the regularity of the drops and the inconsistency with all the other data, I’d say that’s some kind of logging or processing error. Try opening the same log in the webtool and see what it comes back with.
More context required here. What flight controller? Post a link to that .bin log file.
That log has a lot of periods of not-flying, that I wonder if that’s confusing the MP FFT tool.
You don’t need the harmonics. The 1st order is doing enough.
INS_HNTCH_FM_RAT,0.8
INS_HNTCH_HMNCS,1
INS_HNTCH_BW,20
Actually we fly and then land disarm two times but only one big log file found instead of 3 flights
That Flight Controller only has one IMU so not sure why Mission Planners review tool is showing data for 2. In any case @Allister is right, this tool is obsolete.
And set INS_LOG_BAT_OPT to 4.
Or better, disable fast harmonic in the log bit mask and the disable batch logging and configure for Raw logging with bitmask 9.
Many thanks What about the vibration is it acceptable in this log
No. Vibe-X is too high with a few clipping events.
I received a 3 in flight yaw alignment and nearly it was going to crash. Maybe this time we got high vibration values.
Your vertical acceleration controller gains are misconfigured. And are you sure of the Motor Range parameter settings?
Yes checked and I confirmed now again
Because here Motor 3 is bouncing off the bottom usually indicating that MOT_SPIN_MIN is too high.
And again the PSC_ACCZ parameters are way off from Hover thrust.
OK clear there is one thing I notice after reversing one motor in Blheli32 configurator the once plug the battery motor are not beeping ate same time like before. parameters set
| PSC_ACCZ_I | 0.25 |
|---|---|
| PSC_ACCZ_P | 0.125 |
All of the issues (bad logging, incorrect PSC gains, incorrect Min) you found so far are avoidable by using the ArduPilot methodic configurator software
You will also find other miss-configurations, and all are avoidable. Can you afford to miss-configure your vehicle?
