VESC crashes on Servo output

Hello everyone,

I have a VESC 6 MKV that I am trying to use to control a F1Tenth-type Autonomous RC-Car. I have flashed the VESC with the newest (servo_out enabled) Firmware (5.02). The motor and servo of the car are controlled over the VESC ROS driver (https://github.com/f1tenth/f1tenth_system/tree/master/vesc).

Enertion FOCbox question

ENERTION FOCBOX

So completely disappointed in what a struggle it is to use VESC tool on this unit. I have never had such trouble with even older ESCs. I've never had to jump through so many hoops or execute so many specific, special operations just to get firmware flashed that allows the thing to function properly.

 This is a Vedder unit, v1.6 - HW4.12.  
I don't want to, and shouldn't have to dedicate a part of my life to software expertise in order to program a VESC so I can ride my skateboard.

Just blew the FETs out of two V1.6, HW4.12 VESCs after re uploading firmware.

could not run .48 firmware because of motor temperature sensor fault when attempting auto detection. 
This all started when I accidentally looped current and blew out the UART transceiver when I reconnected a pair while powered up. A bone head move I'll admit.
I would have expected some protection against this would be built in. I expected wrong.

What is the best way to make an emergency button to stop the motor from spinning?

Hi,
what do you think is the best way to integrating the emergency switch with VESC? I want to make a robot and when it goes out of control safely stop it with an emergency push button. I can think of few solutions, for example, when the button is pushed send a command to the vesc to set velocity to zero but what if vesc in itself will malfunction would it be better to cut off the power from vesc?

Do I need phase voltage sense?

Submitted by Flepple on Mon, 2021-01-25 15:31

Hi,

at the moment I am wondering about if I need phase voltage sensing for the motor control. I am designing my own hardware with the VESC Software. I will use BLDC mode and Current control. Is it useful to measure the phase voltage or do I need it for the software control? I didn´t find anything yet. Usually traction inverters don´t have phase voltage so I did not find any advantages. 

Does somebody have experience with that? 

Thanks and best regards,

Flo
