Hi my board started acting strange so I connected it up to Vesc Tool.
I have 2 x 4.12 vesc’s running firmware 4.12 HW version 410.
To simplify matters I have disconnected the working vesc and motor and I am just using the faulty motor or vesc.
When I try and do a motor test on the faulty one I get Detection failed reason -11
The vesc connects and shows the proper data so vesc seams to be reading and writing fine.
When i do the calibration for the motor on this one it sometimes makes a loud screech noise very short and i get the -11 error. I have checked the power which is good and the vesc seems to be working fine. Is there a test that I can do to see if the motor is the problem and failed or its the vesc?
You can check the motors by first turning with the hand and see if it still moves freely (no broken magnets or bearings). Than take a multimeter and Check the resistance of all phases against each other. The resistance should be close to zero but for all combinations it need to be the same value. Also check each phase to ground (stator or bell on a place where it’s not covered with color) that should be in each case open end.
Also check solder joints on the bullet connectors and try to setup your vesc with and without connected sensor wires.
OK i think I am getting somewhere. The motor is working with the working vesc. So it seems the vesc is to blame. I sent the pictures above of the culprit vesc. I think I need to send it off for a repair which the person apparently does. Any more advice would be cool though.
I think your right. I get 3 blinking red lights when I try and do anything with the motor. Vesc starts fine blue and green light, reads and writes fine. I also get a -11 error sometimes which is bad connection regarding to the motors.
