Connection Diagramm Octocopter Quad X Motor Pin


(FRED) #1

Hello everybody,
I have an Emlid Edge System in my octorotor X frame for the first time.
Unfortunately, I have nowhere found on which pins and what order the motors are connected?
Motor 1, 2, 3,4, 5, 6, 7, 8
In addition, the question where exactly, at which pins are the relay outputs defined?

thanks in advance!

Hello,

Arducopter Wiki is the place to look: http://ardupilot.org/copter/docs/connect-escs-and-motors.html

Your setup is not good…

Relay output could be 9 to 12.

Hello,

No confusion: Emlid Edge is an Ardupilot (Arducopter) compatible unit.

So, Arducopter wiki is relevant for the most part. ( Edge QGroundControl version is different from standard used with Pixhawk )

ESC 1 to 8 have to be plugged on Out 1 to 8 of Edge.

Out 9 to 12 are free to use with accessories (Camera and gimbal control, external lights,…)

RC in (your receiver) is on R>
S< is an sBus out (use to be confirmed by Emlid)

Hello, that’s exactly how I did it.
But when I do the engine test in the QGroundcontrol software, the order of the engines is not correct.
The motors are marked in the software with ABCDEFGH.
If A is the engine number 1 and B is the engine number 2, then this does not correspond to the official engine order the standard is for Quad X Octocopter.

Motor test order:

A1, B6, C4, D7, E3, F8, G2, H5

Sorry, it is not easy and maybe not well documented.

Clockwise from front right, top then bottom to front left. http://ardupilot.org/copter/docs/connect-escs-and-motors.html#checking-the-motor-numbering-with-the-mission-planner-motor-test

So i understand the logic behind this order.
I hope that EMLID will describe this in their software or in their documentations.
Many thanks for your answers!
