Hi,
I am having an issue while trying to use the ESC32 with my 390KV 4225 motors (16 pole).
It works, as long as I don’t change throttle either too slow or too fast.
When I increase throttle very rapidly, the ESC disarms.
When I increase throttle very slowly, the ESC also disarms.
If I move throttle up and down in a smooth swing, everything works fine. Of course, in a multirotor it needs to be able to do rapid rpm changes.
I had prepared two video clips that show my problem, but unfortuntaly this forum does not allow a new user to include links to external sites when posting.
I cannot complete a current-limit calibration, because it does the same in the middle of the routine: at some point the ESC stalls and disarms itself.
I tried both the release firmware v1.4 and the “Version 1.4.1 Build 5251”.
The only settings I changed from the default in the ESC setup are:
Max current = 15
Motor poles = 16
PWM start min = 1100
PWM min value = 900
PWM low value = 1105
Is this something I can fix with any of the other settings? Should I be looking at the minimum and maximum commutation period setting? Or the switch frequency? And if so: how should I change these? Increase or decrease?
Any help/advice greatly appreciated.
Thanks & regards,
Johan.
