Broken AX-12 Used As Rotational Sensors

The electronics can handle that temp. no problem.

The default high limit temperature is 85 degrees C.

The max torque is preset to 1023, but that is a setting rather than a limit. When you put too much torque on the servo, it will heat up fairly quickly.

If you look at page 16 of the AX-12 manual, it spells out how the alarm function works, both in flashing the LED and shutting the servo down.

Broken AX-12 Used As Rotational Sensors

I don't have access to my Bioloid at the moment, but are the AX-12+s defaultly set to protect itself from overload and temp? I remember in the manual that it had some value to "85" for temperature limit. Does this correspond to 85 celcius? If it is, I need to set all of my servo to a lower limit since I don't want any of the electronics inside going anywhere near this temp since most ICs are rated there (unless it has automotive spec).

What are the AX-12+ set at for protection of over current/load, and over temp?

Its pretty hard to burn out an AX-12, unless you disable the torque and termperature limit system...

Has anyone experimented with using an AX-12+ with a burned out motor as a rotational sensor?

I was recently doing some brainstoming about master/slave rigs and realized that you might be able to use an AX-12 as a sensor. One could remove the motor and gears and just use the horn, it's axle, the controllerboard, and the housing.

It would probably be a good use for an AX-12 with a burned out motor, assuming circuit board was undamaged.
