Problems with 100% throttle input

Submitted by levin on Wed, 2023-11-08 08:32

Hi,

my name is Levin 

I am using an vesc 6.7 Pro with an e-scooter hub motor.I have set the motor in the Vesc software and can also run it via the computer. However, as soon as I use a different input (thumb throttle), I have problems at maximum input. This manifests itself in the way that the motor's speed drops slightly, makes strange noises and negative current peaks of -2.5a are reached. The problem becomes less if I limit the motor current from 50a to 10a. However, that is not my goal. The same problem occurs with another input such as ppm.

Is switching to reverse and giving a bit of current the same is braking?

Hi all, BLDC FOC motor in a project car.  I have current w/reverse button as ADC 1.  While traveling forward, is switching to reverse and giving slight throttle okay to slow?  Is it effectively the same as braking?  

PPM, REWIND and FORWARD in same rotation

Hi,

I convert a Mercury 9.9 to electric.

Propeller direction ist switched with the outboard gear, so the electric motor must spin only forward.

The Throttle should work like in a motorboat, with neutral, forward and reverse.

I am looking for a Setup of the PPM using Centered Control, but in both direction of the Throttle, the Motor should spin forward.

Is this possible?

Thank, for any Help

BATTERY_VOLTAGE_HIGH_CUTOFF_START // CUTOFF_END ?

Submitted by Andy G on Mon, 2023-10-16 18:41

Hi,

Are there still plans to implement "Battery Voltage High Cutoff Start" and "Battery Voltage High Cutoff End" that is, in theory, the exact opposite of the Battery_Voltage_Cutoff_Start // End script that is already implemented?  I realise braking will be less consistent when the battery is >95% full, but I cannot afford to keep buying / repairing VESCs.

Multiple questions about vesc control

Submitted by Tripod6813 on Sun, 2023-10-15 20:03

Hello all,

 

I have a project right now where I am controlling a vesc using vesc uart (https://github.com/SolidGeek/VescUart) and an esp32.

 

This works quite well so far. However, I still have a few questions that hopefully one of you can answer.

 

1. vesc uart does not seem to give me the battery level. Where can I find the function. How on a vesc this is calculated? Then I would just calculate this in my esp32 code.

 

Setting up flipsky

Submitted by JanneHooo on Sat, 2023-10-14 13:07

Hello. I am trying to setup flipsky Mini FSESC4.20 50A base on VESC® 4.12 to work with ardupilot (or PPM input). Should this be possible? When I have battery and USB connected, everytime I change And write Control type to be PPM it changes to uart. On help page it asks to restart controller and to teach endpoints. But how can one restart? I have brushed dc motors that I managed to get turning via vesc tool
