Please share a screenshot of the Run tub of Roborun+ when the controller is connected and powered on. Please drop down and select Battery Volts and Controller Volts in the capture window to show these in the screenshot:



Please also attach your motor controller configuration file (Configuration Tab > Save Profile to Disk)

Put it in a .zip file then you can attach the .zip. Otherwise you are welcome to send it directly as a .xml to This email address is being protected from spambots. You need JavaScript enabled to view it.

Please also include the screenshot in your .zip because the attachment you made is too small I cannot expand it to see it

Received, thank you.

The reason you are getting the UnderVolts fault is because you do not have your battery connected to VMOT. You need to connect at least 12V to VMOT which is the thick red wires on your controller

Please use a volt meter to test the voltage at the contact point of the VMOT wire (red) and your battery. If this point measures 14.5V then it is likely that there is a damaged component in the motor controller.
