Myxa ESC Telega Vendor Specific Status Code

[dynamicmelody (Matt)]

Hello, a couple of our Myxa ESCs have a Warning message as their health status (health: 1 # WARNING). Through the Babel and UAVCAN GUI Tool on our UAVCAN v0 (DroneCAN) CAN bus, we see a vendor_specific_status_code: 3072 (shown below).

Node 12 is one of our Myxa ESCs running Telega v0.4, and I was wondering what status code 3072 might be? Is there a list of status codes for Telega-based ESCs that might be available? Thanks!

The list is available in our knowledge base. In your case, the warning is caused by a mild regression in v0.4 that is addressed in v0.5 — the controller reports a low motor temperature warning incorrectly. Updating to v0.5 should resolve this.

Telega v0.5 is released

As always, grab the binaries from files.zubax.com. This release brings the following improvements: Improved stability of sensorless control under difficult operating conditions such as rapid acceleration or step load change. Reduced the default PWM frequency from 47 kHz to 32 kHz while at the same time reducing the state estimation errors thanks to new DSP architecture. This change reduces the switching losses and thus lowers the heat dissipation in the inverter. Implement feed-forward…

I found the list of VSSCs on the knowledge base but I struggled a couple of times with linking the VSSCs I get from the DroneCAN GUI with that list.

1. can you include a link to the VSSCs? To make sure we’re all (literally ) on the same page.
2. Maybe I’m missing something about translating from the Decimal number I get from the DroneCAN GUI to the list on the knowledge base. Can you use the error code @dynamicmelody descried to give an example?

Thanks

That particular error code was missing, but I fixed it just now. We are working on a comprehensive user guide that will include all relevant information in one place.
