This question is directed to anyone running dynamixels. I am wondering if any of you have attempted or found a way to override the thermal cut off. I've looked thru the Dynamixel wizard and the documentation is lacking to say the least. In a perfect world the ability to turn off these safeties would be ideal.
I'm trying to either override the thermal, default is 70 deg c temp can be set (0-99 deg c) and turn it off OR override that torque goes to 0 when temperature reaches over the thermal cut off.
The Alans I have on the other side of the world are thermal shutting down do to a hot environment. We are going to be working to cool the area but it would be better to override the protections (I'm sure voiding the warranty) or the ability to change the settings in software.
The Dynamixel Wizard will allow you to set thermal cut off anywhere from 0-99 deg c and change the torque settings but I do not have access directly to Alan and would be better to have a software solution. Right now Alans have to be turned off and the motors to cool down for 20-30 min to reset the thermal and bring them back online.
An example of a fix would be adding two buttons to the EZ Robot Dynamixel plug in so one could change the thermal settings and or change the torque setting if thermal limit is reached. I assume those could be added as we can turn on and off the leds, rename Ids and change baud rates within the plug in.
Any help would be appreciated.
you can see the settings for the thermal shut down at 5:05 on this video.

What about this connection?
swap the the EZ-Robot cable (white-red-black) with a dynamixel cable (3 black wires). It helps matching the D5 (colors).
Like this?
Please check the cable colors match the correct dynamixel 3 pins.
1: GND - BLACK
2: BATTERY - RED
3: EZB D5 - WHITE
The hub is useful if you want to power the servos directly:
1) connecting 3 wires you are powering the EZB
2) connecting 2 wires (White + BLACK) you can power EZB with a different voltage e.g. 7.4
Here's another.
EDIT 1:
The colors are inverted on the EZB side ?
EDIT 2:
It seems they are inverted also on the hub side...
Q: Why not match the colors and the pin position ?
I'm without clues.
You need to try the servos with the original vendor software.
Check the Id's and the baud rate.
