Configuration of your VESC® or VESC® based ESC using the VESC®-Tool Software.

In this tutorial we will configure multiple genuine VESC® motor controllers, using a CAN bus link cable. We will use a PPM signal based radio controller and will run the VESCs in Current No Reverse with Brake mode.

Make sure to use the latest VESC-Tool version!

Important Notice:

Run the Motor Setup Wizard on each VESC first.

Never connect a receiver or other devices to multiple VESCs (e.g. Y-PPM).  Use CAN-Bus instead.

Only connect CANH and CANL In the CAN connector. 5V and GND should be left unconnected. 

Failing to follow these instructions may damage your VESC (s) permanently.

Now we will start to configure the master VESC. This is the VESC with the input device (e.g.reciever) attached.

Connect your master VESC® to your computer using a mini/micro USB cable.

Mini USB is used for HW 4.xx only. Some cheap micro USB cables are designed for charging your
phone and will not work properly! Try another cable if you experience any issues.

Run the VESC®-Tool software.

Agree! It's important to ensure that all settings are correctly configured and that each VESC is properly connected to the CAN-Bus network to avoid any issues with communication or control. Testing the setup thoroughly before use is also recommended to ensure everything is functioning as intended.
