I´ve mistakenly connected the Dynamixel XL-320 (Blue Servo) with the Dynamixel XL-430 (Joint 5), because we were missing a cable on our Niryo One, after fixing that issue we couldn´t get the Niryo running again. So we connected the Dynamixel XL-320 in series with the XL-430 12V instead of 7 V. The error is: Missing Motor Connection. The Dynamixel XL-320 starts to get hot in idle use and after a while it starts flashing the red error LED. We assume it is now broken, is there a way to identify the issue further or do we need a new one?
It seems that the Dynamixel XL-320 is burnt. As you said you applied 12V instead of the recommended ~7.4V.
Could you describe how you were able to connect an XL-320 with an XL-430 ? The connector are not the same and it’s not possible (unless you create your own connectors) to connect the 2 motors together.
Also, please issue a “Technical Support” ticket here, explaining what parts were missing and what is broken, so we can get back to you quickly with a solution. Thanks!
