DYNAMIXEL Actuator

XL330-M288-T

I am trying ros2 run dynamixel_sdk_examples read_write_node.
Read command seems to work fine, but write command gets error message,

[RxPacketError] Hardware error occurred. Check the error at Control Table (Hardware Error Status)!

The video attached to your issue shows that you are exceeding the operating voltage of your DYNAMXIEL servo, resulting in an overvoltage error.

Your XL330-M288 servo has a 6v operating voltage maximum.

Hi! See that VOLT Error Indicator on your Wizard 2.0

Could you please help me on this? ROS2 (Humble) + Dynamixel Error

I also asked on ROBOTIS Github but I haven’t gotten any reply yet.

@Jonathon
Following your advice and correcting the over voltage issue, my motor works fine.
Thank you so much!
