Hi,

can you please elaborate on the "speed limit" (UART command 0x9C)? Does 
the onboard µController set this in the firmware or is it derived from 
measurements or can the user set this (in that case you forgot to add 
the according write command)?

I assume, it is in RPM?

Best,

Illylonka

Hi, 

The speed limit at the moment is used in the Position Control, which will define the maximum speed that the motor can reach during following the position reference, and yes, the unit is in RPM and we will update our user_manual, thanks for mentioning, to know more about it you can take a look at our "Digital Position Control using Quadrature Encoders Examples" section in the User manual. it's basically a safety measure.

@staff Thanks!

Please keep me posted, e.g. put it into the Changelog of the next firmware update, if you change the meaning.

Hi @illylonka,

sure, as the name of the command suggests, it will be used for safety measures, in future versions, the Speed Limit will be used for Speed and Torque controllers as well, just to make sure if the motor for any reason went above the requested Speed Limit, SOLO stops the operation and reports the error back to the user or it forces the motor to remain below the speed limit. This feature now doesn't exist, but the idea will be sth similar.

Milad
