pixhawk + DJI E7000 motor doesn't stop

Hello, everyone.
I made the Hexacopter using DJI E7000 and pixhawk.
I found a fatal problem in my Hexacopter.

When some ESC connect with power, the motor starts to rotate at low rpm(lower than arming).
When you land after the flight, it also rotates at a low rpm(normal only when the motor stops).
The ESC LED color is…

  • Motor that rotates on disarming after landing : green
  • Motor stopped when disarming after landing: Red
  • The other one: Rotate to the yellow/green blinking

This has never happened in E2000+pixhawk.
Can I solve the problem?

Good day, did you perform radio and esc calibration?

Yes,you should calibration the esc.

Have you set MOT_PWM_MAX & MIN correctly?

Thank you for your answer.

I have many experience in making a lot of drones and finished setting without any problems.
However this case, I adjusted the position of the ESC from the motor mount.
This results in longer three-phase electrical lines for the ESC and motor.

Can it cause noise or problems in the motor?

Post some pictures of setup with a log by setting LOG_DISARMED=1.

Thank you for your attention.

What parameter values should I tell you?

The picture below is the ppm setting of the motor and the radio you mentioned first.
If you can care it, I can send you the entire parameter value, flight log, video, etc.
Also, the log value was not obtained in disarmed state. Because the symptoms occur intermittently.


The second picture is what was needed. You haven’t setup MOT_PWM_MAX & MIN. This is usually a fixed value provided by DJI.
Example: MOT_PWM_MAX=1960, MOT_PWM_MIN=1160

Yes, I understand.
Do you mean I have to input the PWM min_max value?
Because it may be different from the value provided by dji?
Then I will enter the pwm value of dji that you told me.

Okay, thank you very much for your answer. I will contact you again after the test.
