Motor control issues with the latest version

I found sonething interesting.
When I use Ardusub version 4.1 and above, I find that the number 5 motor does not work, however when using version Ardusub 4.0.3, the number 5 motor works fine. I don’t know how to fix it, is there can anyone help me?

The hardware environment is BlueRov2 Heavy

I use QGC test the motor No. 5, by pulling down the amplitude bar of motor No. 5.

Hi, can you try reverting to firmwre default parameters?
In QGC → vehicle → parameter → tools

Yes, but it doesn’t seem to work

Hi @suitangxiaoyi,

If changing ArduSub versions causes the motors to not work then there’s most likely something wrong with your parameters, or there could be a bug in ArduSub. Given you’ve mentioned you’re using the current stable version, it’s more likely to be a parameter issue.

  1. Does the motor work in the Motor Test page, or not at all?
  2. Can you confirm the following parameters?
    Parameter Value
    SERVO5_FUNCTION Motor5
    SERVO5_MIN 1100
    SERVO5_TRIM 1500
    SERVO5_MAX 1900
    MOT_PWM_MIN 1100
    MOT_PWM_MAX 1900
  3. If those parameters are fine, are you able to save your parameters to a file and upload them here? :slight_smile:

Thanks, now the motor N0.5 works fine.
If so, can you provide parameters for the campass? Because my compass calibration is always unsuccessful.
